“…It is very clear that materials management plays a vital role in the construction industry regardless of the contractors' classification (whether micro, small, medium, or large). The literature review also proved that large contractors are effectively implementing materials management in the various stages of a project and tend to integrate materials into the early stages of project planning [18], [20] due to the availability of resources. In addition, the table also clearly shows that most of materials management studies in the industry have been devoted to large construction companies.…”

“…The list consisted of six categories which applied to facilitate the implementation of effective materials management: accuracy, quality, quantity, cost, timeliness and availability. In continuation, Al-Khalil [15] applied Plemmons' [19] findings by assessing the effectiveness of 17 industrial construction projects using his criteria [20]. The findings revealed that most of the projects have been implementing effective materials management and the criteria tend to be achievable in the large construction firms.…”

Materials management is a vital element in managing projects as materials contribute more than 60% of the total project cost. It also plays a key role because the success of every construction project relies heavily on having materials on time and at a reasonable cost. Thus, it affects the overall project performance. Despite the importance of materials management for construction projects, construction contractors are still suffering from the loss of productivity, project delay and cost overruns due to the absence of proper implementation of materials management. Therefore, the aim of this paper is to review the state of the art of materials management research in the construction industry. A literature review from books, journal articles and conferences papers related to this topic was carried out. Findings show that previous research related to materials management studies were focused more on large construction contractors while small and medium contractors have received little attention. Hence, a study that focuses on the small and medium contractors is needed as this group undertakes more than 90% of the activities in the Malaysian construction industry.

“…Caron et al (1998) presented a simplified model to plan the delivery of materials to building projects, which could be used in early project planning stage. Plemmons and Bell (1995), and later Al-Khalil et al (2004), established indicators for the measurement of effectiveness of material management systems. Horman and conducted an exploratory study of the effect of material inventory buffers, being a fundamental parameter in any material management system, on project performance.…”

Purpose -To develop a systematic procedure and a computerized tool for optimizing the delivery and inventory of materials, as part of a comprehensive material management system in construction projects. Design/methodology/approach -A newly devised approach that employs genetic algorithms (GAs) for the optimization of material delivery schedules and their associated inventory control is presented. The approach is based on the project material requirement plans, and employs an objective function that minimizes the total costs associated with material deliveries. Furthermore, the computer system developed is used to examine and validate the adopted approach. Findings -GA proved to be a satisfactory approach for optimizing material delivery schedules and its associated inventory levels. The selected case study particularly showed the system to produce material delivery plans that have reduced costs compared with their actual counterparts. Also, the computer processing time for developing the optimized plans was rather minimal, which promote its practical use.Research limitations/implications -The paper addresses one part of the comprehensive material management system; that is the optimization of the material delivery schedules and inventory control. Other future publications by the same authors will address the issues of probabilistic lead time calculations and development of material ordering schedules. Originality/value -The paper partially fulfills a long-sought research need for developing comprehensive material management systems specifically tailored to construction projects. The system takes into account several parameters that are not typically incorporated in the economic order quantity models for material management. Furthermore, practicality of the introduced system is augmented by the fact that it is interlinked with one of the most commonly used scheduling software.
