This paper develops an integer programming approach to two-sided many-to-one matching by investigating stable integral matchings of a fictitious market where each worker is divisible. We show that a stable matching exists in a discrete matching market when the firms' preference profile satisfies...

We present a new mixed-integer program for a multi-depot, multi-vehicle capacitated location-allocation routing problem (LARP). The model simultaneously selects the locations of facilities, allocates customers to the intermediate facilities, and identifies the optimal number of capacitated...

Independent ATM Deployers (IADs) are emerging companies that own and operate Automated Teller Machines (ATMs) independently of banks or financial institutions. Cash logistics is the primary process of these companies, and its profitability directly depends on the type of modules chosen as a...

In manual and semi-automated order picking systems, one of the challenges consists in minimizing picker blocking. One of the ways to prevent picker blocking is to have wide-isles warehouses. Although this solution solves part of the problem, pick-face blocking remains a challenge. Technological...

Scheduling problems occur in a broad range of real-world application fields and have attracted a huge set of research articles. However, there is only little research on exact algorithms for scheduling problems, many of which are NP-hard in the strong sense. We investigate the problem on a...

This work proposes a variation of the location-routing problem (LRP), a problem that interconnects two well-known N P-hard optimisation problems: the vehicle routing problem (VRP) and facility location problem (FLP). There are many mathematical formulations and solution methods for a number of...

The Facility Layout Problem (FLP) is a classic problem for industrial engineers and work area designers, taking relevance because of its direct impact on productivity and efficiency in the productive systems. On the other hand, we face the Unequal Area Facility Layout Problem (UA-FLP) when the...
