Operations research (OR) is concerned with scientifically deciding how to best design and operate people–machine systems, usually under conditions requiring the allocation of scarce resources. This publication, one of a series, is offered to supervisors, lead people, middle managers, and anyone who has responsibility for operations planning in manufacturing facilities or corporate planning over...

this paper introduces the general framework of a new system for material flow planning and operations and some of its important aspects. the justification for the new system stems from the short coming of mrp  i/mrp ii in term of its assumptions, particularly in relation to fixed lead times and effectively infinite production capacity. at the heart of the system is an automatic scheduler based ...

This is a sea story about using a simple classroom example to save a great deal of money, as well as to convince beginning Postgraduate Naval School operations research students—experienced, skeptical military officers—that mathematical analysis can yield immediate results. The application is planning a ship’s transit from one point to another in a fixed amount of time, given that the ship can ...

Linear programming is a tool that has yet to reach its full potential in power system engineering. To illustrate in a tutorial style how it is currently being applied and how its use evolved, applications are outlined in three areas: generation scheduling, loss minimization through allocation of reactive power supply, and planning of capital investments in generation equipment. The applications...

In humanitarian relief operations (HRO), due to the excessive number of relief organizations, multiple organizational coordination is a demanding and complicated task. Considering such a problem, this paper proposes a two-phase mechanism to coordinate multiple heterogeneous relief organizations in a decentralized HRO logistics network. To address such a problem, first a bi-level mixed integer l...
