The objective is to maximize the profit which is calculated by a cost model of sales revenues, production costs, storage costs, and penalties for lateness and for finishing line start-ups and shut-downs. The cost model adds some equality and inequality constraints with associated real valued variables for the sales, deficits, and the storage, but it does not further restrict the feasibility of the production decisions. 

The use of pesticides in stored products in tropical countries cannot be separated from the broader field of economics and engineering. In order to use more pesticides efficiently, storage structures must be built. They, in turn, must be suited to the needs of the country and located so that they may be used economically. The jute bag is a poor, but costly storage unit. Its cost should be compared with steel or concrete over a period of 30 or 40 years. With improved facilities, a steady increase in the use of pesticides will be seen. Management must be improved also to install sanitary practices along with efficient and sensible use of pesticides. Because of the distances involved, freight rates are important and because of the small dosages required, methyl bromide is favored thereby.

Natural gas constitutes an important energy source as it provides the lowest emission of C02 among fossil fuels. In addition natural gas is widely used as feedstock for the petrochemical industry, such as methanol and ammonia production - and may on a future perspective also have a potential for bio-protein production. The only disadvantage of natural gas seems to be a fairly costly storage - either as under ground (UGS) or compressed or in condensed phase (CNG, LNG). 

The lowest-cost storage is likely to be at EOR sites. Today, the oil industry pays about 10 to 15/t C02 (roughly, 40 to 60/t C) for C02 delivered to the EOR site (Kuuskraa and Pekot, 2003). In the United States in 2001, about 10 Mt C/yr were injected for EOR, enhancing domestic oil production by 180,000 barrels per day (bbl/d) (Hill, 2003), or about 2 barrels of oil produced for each metric ton of C02 injected. 

The next-lowest-cost storage is likely to be at depleted oil and gas fields, where reservoir geology is already known, wells suitable for injection of C02 may have already been drilled, relevant permits may already exist, and subsurface rights may be well defined.

Compression characteristics are extremely important for bulk size reduction operations (Murthy and Battacharya, 1998), especially in military and domestic applications. Compressed powders can be used by armed forces for field rations, by astronauts during space travel, and by hikers and others who must carry their own food supplies. Powders can be compressed by mechanical presses with savings in transportation costs, storage space (Van Heyst, 1983), and packaging material. Webb and Hufnagel (1943) reported a 42% savings in space with compressed dry whole milk (Van Heyst, 1983). 

The first term on the right-hand side of the equation is independent of current density, such as the cost of sub-raw materials, pretreatment cost, storage tanks, etc., the second term is proportional to current density, such electric power consumption for electrodialysis or electrolysis, and the third term is inversely...

Consider a supply chain of three levels in series shown in Fig. 3.10. The first and most upstream level (Level 1) has two factories in parallel producing two major products, FI and F2, in full production capacity of 168 h (24 x 7) a week. They both feed a distribution center (DC) in Level 2 and deliver to a common customer in Level 3. Products can also be delivered to the customer by the distribution center. Both factories have no room for finished goods storage and the customer does not want to receive any early deliveries. The medium term planning production timing and quantities that minimizes the total cost of production cost, storage cost, transportation cost, tardiness cost for the whole supply chain over a 4 week time horizon, (the unit of time being one week). The transportation time from any one of the two factories to the DC, firom any one of the two factories to the customer, and from the DC to the customer all transportation times are assumed to be identical and equal to one week. 

Minimize the total of the production costs, storage costs, transportation costs, tardiness costs, and penalty costs for non-delivery over a horizon of 4 weeks. The problem is formulated as a Mixed Integer Program as follows ... 

The Total Fixed Investment is the total capital cost of the plant. It includes land, the battery-limits costs, storage, utilities and general service facilities, spare parts, preoperational and startup cost, project management and interest during construction. The Total Depreciable Fixed Investment excludes the cost of land, which is not a depreciable cosfitem. . ... 

Processes such as pyrolysis and combustion reduce the volume of solid wastes and, in particular, plastics waste. Solving the problem of the vast volume of plastics waste is often the key to successful solid waste management. Low-density polymers such PE, PP and so on, require costly storage at the point of waste generation, which greatly affects the cost and the logistics of collection and handling. Incineration is an attractive process to decrease not only the volume of solid waste but also reduce the burden on landfill and other disposal operations. Incineration is not a final disposal method as it requires landfill or other means to receive the solid residues.
