Abstract In multistage perfect matching problems, we are given a sequence of graphs on the same vertex set and asked to find matchings, corresponding graphs, such that consecutive matchings as similar possible. More precisely, aim maximize intersections, or minimize unions between matchings. We show these problems NP-hard even in very restricted scenarios. As our main contribution, present firs...

An integrated multistage supply chain inventory model containing a single manufacturer and multiple retailers is proposed to consider deteriorating raw materials finished products with imperfect production inspection systems. The main purpose jointly determine the manufacturer’s delivery strategies retailers’ replenishment maximize total profit. First, individual profit functions of are establi...

In this paper, we develop a multistage approach for estimating the mean of a bounded variable. We first focus on the multistage estimation of a binomial parameter and then generalize the estimation methods to the case of general bounded random variables. A fundamental connection between a binomial parameter and the mean of a bounded variable is established. Our multistage estimation methods rig...
