We study a new class of problems – recurrent projects with random material delays, at the interface between project and supply chain management. Recurrent projects are those similar in schedule and material requirements. We present the model of project-driven supply chain (PDSC) to jointly optimize the safety-stock decisions in material supply chains and the crashing decisions in projects. We p...

Most of the applied and interesting problems in industry and real world are difficult to solve. These problems are often NP-hard and the problem in this paper is strongly NP-hard. Approximation and metaheuristic algorithms are used to find a solution to these problems. In this paper we have used a polynomial time approximation algorithm, this algorithm is a suboptimal approach that provably wor...

We formalize the notion of optimal supervisory control of discrete event dynamical systems (DEDS’s) in the framework of Ramadge and Wonham. A DEDS is modeled as a state machine, and is controlled by disabling some of its transitions. We define two types of cost functions: a cost of control function corresponding to disabling transitions in the state machine, and a penalty of control function co...
