Abstract

During discussions related to an ongoing research for the prospects of using dynamic scheduling concepts in construction industry in several forums, we received in many cases a similar question: What is dynamic scheduling? This is mainly because the dynamic scheduling topic is quite new in relation to construction field; despite of its wide applications in manufacturing and other industries. So, we thought of presenting a quick briefing about the dynamic scheduling’s concepts, approaches, strategies, policies, and applications.

  1. Introduction

Most probably when you hear the term “Scheduling”, especially if your background is construction, then the first thing which comes to your mind is Predictive Scheduling, or preparation of a good quality optimized baseline schedule which is constructible and easy to maintain. This is of course correct; but in real world, and again especially in construction industry, real-time events extremely disrupt the integrity of schedules. And if the responsible project management team does not act dynamically to mitigate the impact of these events, schedules can become very easily neither optimized nor realistic.

Accordingly, the presence and implementation of a predefined Dynamic Scheduling strategy to mitigate real-time events’ disruptions is a must for the successful implementation of projects planning. Dynamic Scheduling is the process of absorbing the effect of real-time events, analysing the current status of schedule, and automatically modifying the schedule with optimised measures in order to mitigate disruptions.

Dynamic Scheduling, as many other scheduling concepts, started and developed in the manufacturing industry; consequently, the majority of approaches, strategies and policies presented in this context were mainly focusing on manufacturing systems and applications. The following sections will briefly review the general dynamic scheduling systems’ components.

Amer Mohey El-Din Fahmy is a Planning Manager, at CCC/TAV JV, Development of Muscat International Airport project. He holds a BSc (Hons.) in Construction & Building Eng. from AASTMT, Egypt; MSc (Hons.) in Construction Management from AASTMT; and is currently a PhD student at Loughborough University, Construction Project Management (expected completion 2014). With 14 years of experience, he held several project management related positions within major construction industry enterprises (such as CCC & Siemens), for large and mega projects related to aviation, power networks, marine works, infrastructure, and industrial facilities; with contractor and consultancy experience in few middle east countries (Egypt, Jordan, Saudi Arabia, UAE, Bahrain, Qatar & Oman). His main specialty is focused on project controls systems establishment, procedural to implementation; especially with respect to integrated controls solutions, either with well-known software packages or with development of in-house oriented IT solutions. Amer’s experience is complemented with an academic background, including research activities within construction automation context, and with teaching experience within the Construction Management track, in the Construction & Building Engineering department, AASTMT, Egypt.

Egypt / UK

Dr Tarek Hassan is Professor of Construction Informatics in Loughborough University (UK) and Director of the European Union Research Group (EURG). Tarek’s first degree is in Civil Engineering, also an MSc in Civil Engineering and another MSc in Construction Management from Loughborough University with distinction. He was awarded his PhD from Loughborough in 1996. His academic experience is complemented by 10 years of industrial experience with several international construction companies as a site engineer, site manager and project manager. His areas of expertise include advanced construction information technology, ICT (Information and Communication Technologies) for energy efficiency, smart buildings, industrialised construction, collaborative engineering, Information Modelling, simulation, virtual enterprise business relationships, e-Business and legal aspects of ICT.

Tarek has been involved in over 17 EU funded projects as Coordinator or partner under the ICT and NMP (Nano technologies, materials and production) programmes of FP4, FP5, FP6 and FP7. He’s got a wide network of European and International partners including Universities, ICT companies, construction organisations, research institutes, consultants, municipalities, etc. He raised research funding of 7 Million Euros and participated in projects of total value of 40 Million Euros. Tarek is engaged in several activities with the EC (European Commission) as an expert evaluator of proposals, expert reviewer of running projects and advising the EC on projects’ performance and strategic research agendas for future calls. He is a member of the ECTP (European Construction Technology Platform), with focus area on processes and ICT. He serves on various international panels for evaluation of proposals including the Academy of Finland and the National Research Foundation of Singapore, funding agents of Poland and Russia. He has been an invited key note speaker to several international conferences and sits on the editorial board of international journals.

Tarek’s research breadth focused mainly advanced ICT to improve energy efficiency in buildings, and with considerable influence on the EC research agenda in identifying research priorities; in addition to researching into dynamic scheduling in construction, engineering higher education and gender aspects within engineering. Tarek’s research output has been reported in high quality journals, conferences and books chapters with a total of over 150 publications.
