In this paper, we consider a parcel delivery scheduling problem of minimizing the total duration for a truck-drone distribution system to serve a given set of customers. The single carrier truck plays the role of a mobile depot of multiple identical

In recent years, efficient logistics has become indispensable, and using unmanned aerial vehicles (UAVs) or drones is promising for considerably reducing the cost and time required for parcel delivery. This paper addresses a parcel delivery schedulin

In this paper, we treat a lexicographic bi-criteria combinatorial optimization model of mixture packaging of two types of items, which arises in actual food packing systems, so-called multi-head weighers. The primary objective is to minimize the tota

We are given a sequence of m machines and an ordered set of n jobs. The n jobs are served by the m-machine system in their indexing order. We are also given a collection of pj machine subsets for each job j ∈ N, where N denotes the set of jobs. We

Given m periodic deliveries performed by a single tractor and a finite set N of cargoes with their arrival times and processing times, we are asked to find a feasible partition of the cargo set N into m disjoint subsets. The workload of a delivery is

In this paper, an iterative improvement heuristic based on the simulated annealing is designed for a weighted item collecting problem in directed bipartite graphs. The weighted item collecting problem is a generalization of an integrated circuit desi

In this paper, a variant of 0-1 knapsack problems in graph structures is considered. Given a directed bipartite structure with a set of items and a set of players, the problem asks to find an arc reversing strategy of the players which collects items

In this paper, a lexicographic bi-criteria food packing problem arising in actual packaging equipments is considered. Given a set I = {i | i = 1,2,...,n} of current n items (for example, n green peppers) with their weights wi and priorities pi, the p
