Decision Model for Selecting Supply Sources of Road Construction Aggregates

Abstract

The authors' recent survey on Polish road contractors' aggregate procurement methods indicates that optimization techniques are rarely used in practicedespite the fact that the material is to be transported from large distances and its sources are inconveniently distributed throughout the country. In search for economy in this respect, the authors propose mixed binary linear programming models to facilitate the contractor's logistic decisions. The purpose of these models is to find delivery quantities from a number of supply locations (of limited capacity and with a limited transportation potential) to predefined destinations along the road in a way that minimizes logistic costs. The problem considered is an extension to the classic transshipment problem, and allows for change of delivery destination along the route with the progress of works, and for constraints resulting from the schedule of the works.

Core Elements Underlying Supply Chain Management in the Construction Industry: A Systematic Literature Review

“…Therefore, planning and control of material flows, involving the mechanisms to ensure the availability of materials at the right time, with the required quantity and minimum cost [48], are critical to the success of a project. Accordingly, many models to support decision making for tasks, such as selection of material sources, determination of the number of deliveries and project scheduling, have been proposed by researchers [49][50][51][52][53][54]. Moreover, studies indicate efficiency potentials in applying collaborative supply networks [47,55].…”

Application of Multiple Criteria Decision Making Methods in Construction: A Systematic Literature Review

“…The second is combined with spatial analysis techniques, such as geographic information systems (GIS) (Gumusay et al, 2016) and spatial database management system (SDBMS) (Díaz-Cuevas et al, 2018). The third is transforming the decision making problem, especially material source selection, into the classic transhipment problem, which can be solved by MODM methods, such as binary linear programming models (Jaskowski et al, 2014).…”

Implementation of Online Reverse Auctions: Comparison of Czech and Slovak Construction Industry

“…Comprehensive evaluation should include associated costs and losses, such as implementation costs, switching costs or higher transportation costs (Emiliani & Stec, 2002), incurred e.g. due to the distance between the supplier and the construction site, that may be large in the construction practice (Jaskowski et al, 2014). Such evaluation may be difficult, since organizations report difficulties in cost assessment (William & Hardy, 2007).…”
