Optimal Design and Operation of Buffer Tanks Under Stochastic Conditions

A Systematic Approach to the Design of Buffer Tanks

Buffer tanks are often designed and implemented for control purposes, yet control theory is rarely used when sizing and designing buffer tanks and their control system. Instead, rules of thumb such as using “10 min residence time” are used. The objective of this paper is to provide a systematic approach. We consider mainly the case where the objective of the buffer tank is to dampen (“average o...

Optimal Relief Order Quantity under Stochastic Demand and Lead-time

In this paper, a newsboy model is developed under uniformly distributed lead-time and demand that is an appropriate assumption in obtaining optimal relief inventory of humanitarian disasters. It is noteworthy that limited historical data are in hand on relief operations. Hence, analytical and approximate solutions for optimal relief order quan­tity were derived. The effect of lead-time uncertai...

Optimal Resource Allocation in Activity Networks under Stochastic Conditions

We treat the problem of optimally allocating a single resource under uncertainty to the various activities of a project to minimize a certain economic objective composed of resource utilization cost and tardiness cost. Traditional project scheduling methods assume that the uncertainty resides in the duration of the activities. Our research differs from the traditional view in that it assumes th...

Optimal Operation of Microgrids Under Demand Side Management

One of the major problem in the optimal operation of the power system is optimal operation of microgrid with regard to the Demand-side-management. From one side, demand-side-management programs  reduce the operating costs of the power system and on the other hand, the implementation of these programs requires a financial incentive policies. In this paper, optimal operation of microgrid with dem...
