Damaturu, the Yobe State Capital is one of the major towns in the semi-arid areas OfNortheastern Nigeria. It lacks adequate water supply. Being a State Capital, rapid improvements in itsinfrastructures including water supply to cope with increased demands are required. Three options forthe expansion of the present water supply system are been considered. These are Groundwater resourceswithin and around the existing system, and surface water schemes from two Dam sites identitied andappraised for this purpose. The Management of the Yobe State Water Board and the State Governmentare faced with the problem of which of these three options to choose. This is a typical capacity expansionproblem within a multicriterion setting in which the choice is to be bassed on economic, environmental,social as well as political considerstions. This paper presents a multicriterion analysis whose result willbe used in forming the basis of an informed decision to be made on why a particular option is to bechosen.

The minimum cost of capacity expansion for time-limited transportation problem on-demand (MCCETLTPD) is to find such a practicable capacity expansion transportation scheme satisfying the time-limited T along with all origins’ supply and all destinations’ demands as well as the expanding cost is minimum. Actually, MCCETLTPD is a balance transportation problem and a variant problem of minimum cost maximum flow problem. In this paper, by creating a mathematical model and constructing a network with lower and upper arc capacities, MCCETLTPD is transformed into searching feasible flow in the constructed network, and consequently, an algorithm MCCETLTPD-A is developed as MCCETLTPD’s solution method basing minimum cost maximum flow algorithm. Computational study validates that the MCCETLTPD-A algorithm is an efficient approach to solving the MCCETLTPD.

This paper presents an optimal production model for manufacturer in a supply chain with a fixed demand at a fixed interval with respect to the learning effect on production capacity. An algorithm is employed to find the optimal delay time for production and production time sequentially. It is found that the optimal delay time for production and the production time are not static, but dynamic and variant with time. It is important for a manufacturer to schedule the production so as to prevent facilities and workers from idling.
