which is a better choosing, plant-to-site or plant-to-plant?Why?

You are the assistant to the manager of the southeastern region of the HazMat Shipping Company. Your boss is in the process of negotiating a contract with a new customer: Southern Chemicals, Inc. The contract is to remove waste from the customer's six plants and drop it at one of three designated waste disposal sites located in the Southwest. While your company is used to transporting hazardous chemicals, this is the first time you will be involved in shipping hazardous wastes. This will impose new restrictions on your drivers in terms of circuitous routes (many towns will not let you bring hazardous wastes into their town limits) and longer transport times (EPA restrictions limit the speed at which a truck carrying hazardous wastes can travel). The estimated costs of shipping (already including the new limitations) a barrel of waste from each plant to each disposal site is given in Table 1 i. The contract would require HazMat to make at least weekly pickups at each plant. The amounts of hazardous waste generated by each plant, each week, is shown in table 2: Taoie L: Hazardous Waste Generated The treatment capacities of the disposal sites are 65 barrels (bbl) at Whitewater, 80 barrels at Los Canos, and 105 barrels at Duras. As a note, your trycks are all the same size and can carry the same number of barrels - so the number of barrels per truck is not relevant for this problem. Besides simply shipping directly from the plants to the disposal sites, HazMat could take shipments from one plant to another, using the plants as intermediate shipping points. This. would allow the company to send only full truckloads across the country. There would be no additional cost to HazMat because Southern Chemicals has agreed to be responsible for all local handling of the waste at both the plants and the disposal sites. The only drawback is the unknown cost of a backlash from the environmental groups who might protest the shipping in of hazardous wastes to the plants. The cost of shipping (in dollars per barrel) between plants is shown in Table 3 below: Table 3: Shipping Costs between Plants A third option: using the disposal sites themselves as intermediate shipping points. The idea here is to get the hazardous wastes to the processing plants as quickly as possible, and then move them around at your leisure (again, moving only full truckloads between the processing sites). Do not make any changes to this solution - just solve it once. There might be unknown costs associated with this option, as the EPA is stringent about the removal of hazardous wastes from the disposal plants. The cost of shipping ($/bb1) between the disposal sites is given in Table 4: Table 4: Shipping Costs verween usposa sites You are the assistant to the manager of the southeastern region of the HazMat Shipping Company.
