“…These heuristics often exploit special characteristics of the problem in question, thus they are not applied to general PVRP instances. Of particular note are , and who all utilize information based on integer programming (IP) to drive their solution procedures, whereas Teixeira et al and Nuortio et al use special‐purpose heuristics and metaheuristics. More detailed information on the applications driving these approaches can be found in section 3.…”

“…Besides garbage and recyclables, collection is needed for other waste products that are generated periodically. Shih and Lin and Shih and Chang model the collection of infectious waste at 384 hospitals and clinics in Taiwan as a PVRP. The motivation for this work is the lack of incinerators, or access to incinerators, and the importance of carefully disposing of infectious waste.…”

The periodic vehicle routing problem (PVRP) first appeared in 1974 in a paper about garbage collection (Beltrami and Bodin, Networks 4 (1974), 65–74). The wide applicability and versatility of the problem has led to a vast body of literature addressing both novel applications and solution methods. This article discusses the wide array of circumstances and settings in which the PVRP has been applied and describes the development of solution methods, both exact and heuristic, for the PVRP. As with many core research problems, many variants have been proposed. We will describe additional problem variants and extensions, as well as discuss the future of research for the PVRP. © 2013 Wiley Periodicals, Inc. NETWORKS, Vol. 63(1), 2–15 2014

“…Nuortio et al (2006) described the optimization of vehicle routes and schedules for collecting municipal solid waste. Shih and Lin (1999) reported an approach to resolve the collection, vehicle scheduling, and routing problems for infectious waste management by using DP and IP methods for the periodic vehicle routing problem in cost only.…”

“…In the first phase, they determine the customers to be served on a specific day and the amount to be delivered, and in the second phase they determine the delivery routes and schedules. Shih and Chang [28] develop a computer system for the collection of infectious hospital waste. Their solution approach for the considered PVRP consists of two phases.…”

A stochastic inventory routing problem for infectious medical waste collection

We consider the problem of designing a logistic system to organize adequate collection of infectious medical waste. Waste materials are produced by patients in selftreatment, stored at pharmacies and picked up by local authorities for disposal. The problem is formulated as a collector-managed inventory routing problem, encompassing stochastic aspects, which are common in such problems. Social objectives, specifically the satisfaction of pharmacists and local authorities, as well as the minimization of public health risks, are considered for the real-world-motivated inventory routing problem. To optimize the planning process for a predefined time horizon, we take advantage of radio frequency identification technology, which allows an improvement of the planning process for pharmacists as well as local authorities. We develop two solution approaches to optimize the determination of visit dates and corresponding vehicle routes. We design a sampling method and an approach based on an adaptive large neighborhood search algorithm to treat the stochastic problem. The suggested approaches are tested on real-world data from the region of Provence-Alpes-Côte d'Azur, in France. To evaluate the performance of the proposed solution methods, the results for different waste collection scenarios are analyzed and compared.
