in this paper, an optimization problem with a linear objective function subject to a consistent finite system of fuzzy relation inequalities using the max-product composition is studied. since its feasible domain is non-convex, traditional linear programming methods cannot be applied to solve it. we study this problem and capture some special characteristics of its feasible domain and optimal s...

In this research, we consider an application of the Bayesian Inferences in machine replacement problem. The application is concerned with the time to replace two machines producing a specific product; each machine doing a special operation on the product when there are manufacturing defects because of failures. A common practice for this kind of problem is to fit a single distribution to the co...

A naı̈ve algorithm for the replacement paths problem runs in O(n(m+n logn)) time, executing the single-source shortest path algorithm up to n times. In our paper [3], we claimed that the replacement paths problem can be solved inO(m+n logn) time for both undirected and directed graphs. However, there is a flaw that invalidates the algorithm for directed graphs. (The algorithm for undirected grap...

There are many reasons for the growing interest in developing new product projects for any firm. The most embossed reason is surviving in a highly competitive industry which the customer tastes are changing rapidly. A well-managed supply chain network can provide the most profit for firms due to considering new product development. Along with profit, customer satisfaction and production of new ...
