+
+**RELOG** is an open-source package designed to optimize supply chains for
+forward, reverse and circular manufacturing. Using mixed-integer linear
+optimization, RELOG helps users determine strategic decisions such as:
+
+- Where and when to build manufacturing and recycling plants
+- The size of these plants, when to expand them, and by how much
+- The sources for each plant's input materials and the destinations for their
+  processed outputs
+- Whether to process input materials immediately or store them for later use
+
+RELOG has been successfully applied in research at various laboratories and
+universities, focusing on areas like critical material recovery from spent NiMH
+and Li-Ion batteries, biomass processing for hydrogen production, and the
+recycling of electronics, plastics and solar PV materials, among others. See
+references for more details.

+# Input data format
+
+RELOG accepts as input a JSON file with five sections: `parameters`, `products`,
+`centers`, `plants` and `emissions`. Below, we describe each section in more
+detail.
+
+## Parameters
+
+| Key                       | Description                                                                                                                                                                                                                                                  |
+| :------------------------ | :----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
+| `time horizon (years)`    | Number of years in the simulation.                                                                                                                                                                                                                           |
+| `building period (years)` | List of years in which we are allowed to open new plants. For example, if this parameter is set to `[1,2,3]`, we can only open plants during the first three years. By default, this equals `[1]`; that is, plants can only be opened during the first year. |
+| `distance metric`         | Metric used to compute distances between pairs of locations. Valid options are: `"Euclidean"`, for the straight-line distance between points; or `"driving"` for an approximated driving distance. If not specified, defaults to `"Euclidean"`.              |
+
+#### Example
+
+```json
+{
+  "parameters": {
+    "time horizon (years)": 4,
+    "building period (years)": [1],
+    "distance metric": "driving"
+  }

+| `variable output (tonne/tonne)` | Dictionary mapping the name of each output product to the amount of output generated, for each tonne of input material, and for each year after the input is received. For example, in a 4-year simulation, if this field equals to `{"P1": [0.1, 0.3, 0.6, 0.0]}` and the center receives 1.0, 2.0, 3.0 and 4.0 tonnes of input material in years 1, 2, 3 and 4, then the center will produce $1.0 * 0.1 = 0.1$ of P1 in the first year, $1.0 * 0.3 + 2.0 * 0.1 = 0.5$ the second year, $1.0 * 0.6 + 2.0 * 0.3 + 3.0 * 0.1 = 1.5$ in the third year, and $2.0 * 0.6 + 3.0 * 0.3 + 4.0 * 0.1 = 2.5$ in the final year. |
+| `revenue ($/tonne)`             | Revenue generated by each tonne of input material sent to the center.

+# RELOG -- Supply Chain Analysis and Optimization
+
+**RELOG** is an open-source package designed to optimize supply chains for
+forward, reverse and circular manufacturing. Using mixed-integer linear
+optimization, RELOG helps users determine strategic decisions such as:
+
+- Where and when to build manufacturing and recycling plants
+- The size of these plants, when to expand them, and by how much
+- The sources for each plant's input materials and the destinations for their
+  processed outputs
+- Whether to process input materials immediately or store them for later use
+
+RELOG has been successfully applied in research at various laboratories and
+universities, focusing on areas like critical material recovery from spent NiMH
+and Li-Ion batteries, biomass processing for hydrogen production, and the
+recycling of electronics, plastics and solar PV materials, among others. See
+references for more details.

+# Mathematical problem definition
+
+## Overview and assumptions
+
+The mathematical model employed by RELOG is based on three main components:
+
+1. **Products and Materials:** Inputs and outputs for both manufacturing and
+   recycling plants. This includes raw materials, whether virgin or recovered,
+   and final products, whether new or at their end-of-life. Each product has
+   associated transportation parameters, such as costs, energy and emissions.
+
+2. **Manufacturing and Recycling Plants:** Facilities that take in specific
+   materials and produce certain products. The outputs can be sent to another
+   plant for further processing, to a collection & distribution center for
+   customer sale, or simply disposed of at landfill. Plants have associated
+   costs (capital, fixed and operating), as well as various limits (processing
+   capacity, storage and disposal limits).
+
+3. **Collection and Distribution Centers:** Facilities that receive final
+   products from the plants, sell them to customers, and then collect them back
+   once they reach their end-of-life. Collected products can either be sent to a
+   plant for recycling or disposed of at a local landfill. Centers have
+   associated revenue and various costs, such as operating cost, collection cost
+   and disposal cost. The amount of material collected by a center can either be
+   a fixed rate per year, or depend on the amount of product sold at the center
+   in previous years.
+
+!!! note
+
+    - We assume that transportation costs, energy and emissions scale linearly with transportation distance and amount being transported. Distances between locations are calculated using either approximated driving distances (continental U.S. only) or straight-line distances.
+    - Once a plant is opened, we assume that it remains open until the end of the planning horizon. Similarly, once a plant is expanded, its size cannot be reduced at a later time.
+    - In addition to serving as a source of end-of-life products, centers can also serve as a source for virgin materials. In this case, the center does not receive any inputs from manufacturing or recycling plants, and it generates the desired material at a fixed rate. Collection cost, in this case, refers to the cost to produce the virgin material.
+    - We assume that centers accept either no input product, or a single input product.

+# Solution reports
+
+In addition to the full output format described in [data formats](format.md), RELOG can also generate a number of simplified reports in tabular data format (CSV), which can be more easily processed by spreadsheet software (such as Microsoft Excel), by data analysis libraries (such as Pandas) or by relational databases (such as SQLite).
+
+In this page, we also illustrate what types of charts and visualizations can be produced from these tabular data files. The sample charts have been produced using Python, matplotlib, seaborn and geopandas.

+# Usage
+
+## 1. Installation
+
+To use RELOG, the first step is to install the [Julia programming language](https://julialang.org/) on your machine. Note that RELOG was developed and tested with Julia 1.8 and may not be compatible with newer versions. After Julia is installed, launch the Julia console, then run:
+
+```julia
+using Pkg
+Pkg.add(name="RELOG", version="0.7")
+```
+
+## 2. Modeling the problem
+
+The two main model components in RELOG are **products** and **plants**.
+
+A **product** is any material that needs to be recycled, any intermediary product produced during the recycling process, or any product recovered at the end of the process. For example, in a NiMH battery recycling study case, products could include (i) the original batteries to be recycled; (ii) the cathode and anode parts of the battery; (iii) rare-earth elements and (iv) scrap metals.
+
+- The model assumes that some products are initially available at user-specified locations (described by their latitude, longitude and the amount available), while other products only become available during the recycling process.
+
+- Products that are initially available must be sent to a plant for processing during the same time period they became available.
+
+- Transporting products from one location to another incurs a transportation cost (`$/km/tonne`), spends some amount of energy (`J/km/tonne`) and may generate multiple types of emissions (`tonne/tonne`). All these parameters are user-specified and may be product- and time-specific.
+
+A **plant** is a facility that converts one type of product to another. RELOG assumes that each plant receives a single type of product as input and converts this input into multiple types of products. Multiple types of plants, with different inputs, outputs and performance characteristics, may be specified. In the NiMH battery recycling study case, for example, one type of plant could be a _disassembly plant_, which converts _batteries_ into _cathode_ and _anode_. Another type of plant could be _anode recycling plant_, which converts _anode_ into _rare-earth elements_ and _scrap metals_.
+
+- To process each tonne of input material, plants incur a variable operating cost (`$/tonne`), spend some amount of energy (`GJ/tonne`), and produce multiple types of emissions (`tonne/tonne`). Plants also incur a fixed operating cost (`$`) regardless of the amount of material they process. All these parameters are user-specified and may be region- and time-specific.
+
+- Plants can be built at user-specified potential locations. Opening a plant incurs a one-time opening cost (`$`) which may be region- and time-specific. Plants also have a limited capacity (in `tonne`), which indicates the maximum amount of input material they are able to process per year. When specifying potential locations for each type of plant, it is also possible to specify the minimum and maximum capacity of the plants that can be built at that particular location. Different plants sizes may have different opening costs and fixed operating costs. After a plant is built, it can be further expanded in the following years, up to its maximum capacity.
+
+- Products received by a plant can be either processed immediately or stored for later processing. Plants have a maximum storage capacity (`tonne`). Storage costs (`$/tonne`) can also be specified.
+
+- All products generated by a plant can either be sent to another plant for further processing, or disposed of locally for either a profit or a loss (`$/tonne`). To model environmental regulations, it is also possible to specify the maximum amount of each product that can be disposed of at each location.
+
+All user parameters specified above must be provided to RELOG as a JSON file, which is fully described in the [data format page](format.md).
+
+## 3. Running the optimization
+
+After creating a JSON file describing the reverse manufacturing process and the input data, the following example illustrates how to use the package to find the optimal set of decisions:
+
+```julia
+# Import package
+using RELOG
+
+# Solve optimization problem
+solution = RELOG.solve("/home/user/instance.json")
+
+# Write full solution in JSON format
+RELOG.write(solution, "solution.json")
+
+# Write simplified reports in CSV format
+RELOG.write_plants_report(solution, "plants.csv")
+RELOG.write_transportation_report(solution, "transportation.csv")
+```
+
+For a complete description of the file formats above, and for a complete list of available reports, see the [data format page](format.md).
+
+## 4. What-If Analysis
+
+Fundamentally, RELOG decides when and where to build plants based on a deterministic optimization problem that minimizes costs for a particular input file provided by the user. In practical situations, it may not be possible to perfectly estimate some (or most) entries in this input file in advance, such as costs, demands and emissions. In this situation, it may be interesting to evaluate how well does the facility location plan produced by RELOG work if costs, demands and emissions turn out to be different.
+
+To simplify this what-if analysis, RELOG provides the `resolve` method, which updates a previous solution based on a new scenario, but keeps some of the previous decisions fixed. More precisely, given an optimal solution produced by RELOG and a new input file describing the new scenario, the `resolve` method reoptimizes the supply chain and produces a new solution which still builds the same set of plants as before, in exactly the same locations and with the same capacities, but that may now utilize the plants differently, based on the new data. For example, in the new solution, plants that were previously used at full capacity may now be utilized at half-capacity instead. As another example, regions that were previously served by a certain plant may now be served by a different one.
+
+The following snippet shows how to use the method:
+
+```julia
+# Import package
+using RELOG
+
+# Optimize for the average scenario
+solution_avg, model_avg = RELOG.solve("input_avg.json", return_model=true)
+
+# Write reports for the average scenario
+RELOG.write_plants_report(solution_avg, "plants_avg.csv")
+RELOG.write_transportation_report(solution_avg, "transportation_avg.csv")
+
+# Re-optimize for the high-demand scenario, keeping plants fixed
+solution_high = RELOG.resolve(model_avg, "input_high.json")
+
+# Write reports for the high-demand scenario
+RELOG.write_plants_report(solution_high, "plants_high.csv")
+RELOG.write_transportation_report(solution_high, "transportation_high.csv")
+```
+
+To use the `resolve` method, the new input file should be very similar to the original one. Only the following entries are allowed to change:
+
+- **Products:** Transportation costs, energy, emissions and initial amounts (latitude, longitude and amount).
+- **Plants:** Energy and emissions.
+- **Plant's location:** Latitude and longitude.
+- **Plant's storage:** Cost.
+- **Plant's capacity:** Opening cost, fixed operating cost and variable operating cost.
+
+## 5. Advanced options
+
+### 5.1 Changing the solver
+
+By default, RELOG internally uses [HiGHS](https://github.com/ERGO-Code/HiGHS), an open-source and freely-available Mixed-Integer Linear Programming solver. For larger-scale test cases, a commercial solver such as Gurobi, CPLEX or XPRESS is recommended. The following snippet shows how to switch to Gurobi, for example:
+
+```julia
+using RELOG, Gurobi, JuMP
+
+gurobi = optimizer_with_attributes(
+    Gurobi.Optimizer,
+    "TimeLimit" => 3600,
+    "MIPGap" => 0.001,
+)
+
+RELOG.solve(
+    "instance.json",
+    output="solution.json",
+    optimizer=gurobi,
+)
+```
+
+### 5.2 Multi-period heuristics
+
+For large-scale instances, it may be too time-consuming to find an exact optimal solution to the multi-period version of the problem. For these situations, RELOG includes a heuristic solution method, which proceeds as follows:
+
+1. First, RELOG creates a single-period version of the problem, in which most values are replaced by their averages. This single-period problem is typically much easier to solve.
+
+2. After solving the simplified problem, RELOG resolves the multi-period version of the problem, but considering only candidate plant locations that were selected by the optimal solution to the single-period version of the problem. All remaining candidate plant locations are removed.
+
+To solve an instance using this heuristic, use the option `heuristic=true`, as shown below.
+
+```julia
+using RELOG
+
+solution = RELOG.solve(
+    "/home/user/instance.json",
+    heuristic=true,
+)
+```

+
+Add piecewise-linear constraints to a JuMP model for multiple y variables.
+
+Creates constraints y_i = f_i(x) where each f_i is a piecewise-linear function 
+defined by the breakpoints (xpts, ypts[:, i]).
+
+# Arguments
+- `model`: JuMP model
+- `xvar`: The x variable (JuMP variable)
+- `yvars`: Vector of y variables (JuMP variables)  
+- `xpts`: Vector of x values for breakpoints (must be in non-decreasing order)
+- `ypts`: Matrix of y values where ypts[i, j] is the y value for the j-th variable 
+         at the i-th breakpoint
+
+# Example
+```julia
+@variable(model, y1)
+@variable(model, y2)
+ypts_matrix = [1.5 2.0; 0.0 1.5; 3.0 0.5]  # 3 breakpoints, 2 y variables
