In our case, we employ Voronoi tessellation to generate a set of random, non-intersecting polygons that represent distinct regions. * We randomly generate locations that fall within one of these regions and assign them one or more waste types: solid, organic, and medical. Each location represents either a residential property, a commercial property, or a hospital. Different priority levels are assigned based on the type: residential properties have a priority of 0, commercial properties have a priority of 1, and hospitals have a priority of 2. * All trucks have a capacity of ${truckCapacity} cubic meters. A residential bin has a capacity of ${wasteVolume.residential} cubic meters, commercial bins have a capacity of ${wasteVolume.commercial}, and hospitals have a capacity of ${wasteVolume.medical}. * We allocate **${inputs.nVehiclesPerRegion} trucks per region**, with one designated for handling medical waste and the remaining trucks capable of handling solid waste, organic waste, or both. * The job of a truck driver is to collect waste from the assigned bins and transport it to the recycling center once all the collection is complete. Once the waste is disposed of at the recycling center, the driver is responsible for returning the truck to the depot. * We utilize the Route Optimization API for each region to find optimal paths for the trucks assigned to service their respective locations. * If there are any waste bins left unassigned in the previous step, we run the Route Optimization API again using the unassigned trucks, but this time, we do it for all regions at once. `44:T58b,viewof inputs = { let shiftStart = new Date(); shiftStart.setDate(new Date().getDate() + 1); shiftStart.setHours(5); shiftStart.setMinutes(45); shiftStart.setSeconds(0); shiftStart.setMilliseconds(0); shiftStart.toLocaleDateString(); return guard(({ template, ...rest }) => { return Inputs.form( { // city: Inputs.select(cities, { // label: "Select city", // format: (x) => x.name, // value: cities.find((t) => t.name === "Columbus") // }), nRegions: Inputs.select( [5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20], { label: "Number of zones", value: 8 } ), nPoints: Inputs.select([50, 100, 200, 250, 300, 400, 500, 1000], { label: "Number of waste bins", value: 200 }), nVehiclesPerRegion: Inputs.select([5, 10, 15, 20, 50, 100], { label: "Number of vehicles (per region)", value: 5 }), shiftDuration: Inputs.select( Array.from(Array(20).keys()).map((k) => k * 0.5 + 0.5), { label: "Shift duration (in hours)", value: 5 } ), shiftStart: Inputs.datetime({ value: shiftStart.toISOString().slice(0, -1), label: "Shift start time" }) }, { template } ); }); }45:T534,{ // Map 1 apiKey; const nbmap = createMap("map", centroid, 10); nbmap.on("load", () => { regions.forEach((region) => { renderPolygon(nbmap.map, region.polygon, region.color, 0.4); }); { const el = document.createElement("div"); el.innerText = icons.depot; el.style.fontSize = "40px"; new nextbillion.maps.Marker({ element: el }) .setLngLat({ lat: depot.point[1], lng: depot.point[0] }) .addTo(nbmap.map); } { const el = document.createElement("div"); el.innerText = icons.recycling; el.style.fontSize = "36px"; new nextbillion.maps.Marker({ element: el }) .setLngLat({ lat: recycling.point[1], lng: recycling.point[0] }) .addTo(nbmap.map); } locations.forEach((location) => { if (!showBins.includes(location.type)) return; const el = document.createElement("div"); el.innerText = icons[location.type]; if (location.type === "residential") el.style.fontSize = "9px"; if (location.type === "commercial") el.style.fontSize = "12px"; if (location.type === "medical") el.style.fontSize = "20px"; const marker = new nextbillion.maps.Marker({ element: el }) .setLngLat({ lat: location.point[1], lng: location.point[0] }) .addTo(nbmap.map); }); }); }46:T48e,selectedRegionsTable = { const result = focusedRegion.result.result; let regionBinIds = []; for (const [locIdx, loc] of locations.entries()) { if (loc.regionId === focusedRegion.regionId) { regionBinIds.push(locIdx); } } const unassignedBinIds = result.unassigned?.filter((_, idx) => idx % 2 === 0)?.map((x) => x.id) ??
