Construction management programs accredited by the American Council for Construction Education (ACCE) are responding to new standards for accreditation, as the accreditation process itself is being changed to primarily focus on learning outcomes. These changes offer an opportunity and a challenge for existing programs to readjust and restructure to meet the increasingly changing expectations within the construction market. Using a network metaphor, with a critical path consisting of critical activities, activity codes, and constraints, can be a successful methodology to develop/align a construction management curriculum. As with any network, this approach can be used as both planning and control tool, being revisited regularly for further fine-tuning responding to the feedback resulting from assessment efforts to “close the loop.” The resulting network can be presented in both tabular and/or graphical format highlighting the critical path and particular critical activities (learning concepts) within that path. Different resources can be applied to the schedule reflecting their commitment and availability limits (space, labs, computers, etc.).

The Critical Path Method (CPM) is useful for planning and control of complex projects. The CPM identifies the critical activities in the critical path of an activity network. The successful implementation of CPM requires the availability of clear determined time duration for each activity. However, in practical situations this requirement is usually hard to fulfil since many of activities will be executed for the first time. Hence, there is always uncertainty about the time durations of activities in the network planning. This has led to the development of fuzzy CPM. In this paper, a new approach of ranking fuzzy numbers using centroid of centroids of fuzzy numbers to its distance from original point is proposed. The proposed method can rank all types of fuzzy numbers including crisp numbers with different membership functions. The authors apply the proposed ranking method to develop a new fuzzy CPM. The proposed method is illustrated with an example.

Ship Repair

The repair and maintenance operations carried out within a shipyard are correlated with the process of ensuring and managing the resources necessary to carry out the works included in the technical specification. Resource planning is a complex issue that can be addressed from several points of view. Initially, the planning of activities is done taking into account only the analysis of the time parameter and the dependencies between activities imposed by the technological process. The practice of the activities carried out in a shipyard has demonstrated that an analysis of the necessary resources according to the existing availability is also necessary. There are many unforeseen situations that can affect both the time of work and resources (material, financial, human) thus complicating the process of planning activities. This paper proposes a way to analyze the resource requirements of a repair project based on available resources, through Critical Path Method diagrams. This provides a comparative view of the daily required profile for a particular resource associated with the project in respect to the daily available profile of the shipyard.

Entrepreneurship is hard work, especially when it comes to the creation of an innovative, ecologically correct and sustainable project, and the small entrepreneur, in addition to facing bureaucratic and fiscal obstacles, has great difficulty in running his business, planning and optimizing his production for lack structured management knowledge. This is what happens with the company studied, where the construction of an educational centre, thought to be a model of ecological and sustainable building, did not have a schedule of execution, thus becoming dependent on very short term planning, accomplished at each step, rather than a structured action as a whole. In this sense, the Critical Path Method (CPM), which uses simple estimates for the duration of the building stages and the PERT technique, was implemented among a variety of schedules and methods for planning and control of works execution. This method is suitable and simple to use by small businesses. This methodology, easy to be understood and implemented, generated benefit to the company, allowing planning, predictability and control of the works.

The Impact

As a result of growing complexities in the construction industry, system dynamics modeling (SDM) has been increasingly used in construction management (CM) research to explore complicated causal relationships at the various levels of construction and management processes. Given the rapid growth of SDM applications over the past two decades, a systematic review is needed to ascertain the state of the art and further trends in the area. This paper provides the results of a systematic analysis of 103 papers from 41 selected peer-reviewed journals from 1997 to 2016. The contributions of the papers are first analyzed, structured and formulated in terms of the year of publication, software involved, the combined use with other methods, and research design. With the assistance of the a keyword co-occurrence network analysis, eight research topics involving different internal and external complexities are identified, including: (1) sustainability, (2) project planning and control, (3) performance and effectiveness, (4) strategic management, (5) site and resource management, (6) risk analysis and management, (7) knowledge management, and (8) organization and stakeholder management. The analysis results reveal the pivotal role of SDM in streamlining different complicated casual relationships at the activity, project, and industry levels across the eight topics and its significant potential in uncovering the impact of complicated contextual conditions on project planning and control, effectiveness and performance, strategic management, and sustainability at the project and industry levels. Lastly, trends and recommendations for SDM applications are provided for future CM research. This paper provides a state of the art of SDM in CM applications and insights into opportunities and useful references for the future.

The fuzzy approach to the project network analysis of the project planning and control is commonly oriented on the fuzzy critical path setting and the project duration monitoring. In the article, this approach is improved by the addition of the project costs perspective to the standard time aspect. The relations for the fuzzy quantity of the total project costs and for its membership function are derived. The example demonstrates the application of the theoretical relations and shows how the enhanced fuzzy approach can be used when different project variants are to be compared. The example also reveals how the fuzzy approach with the project costs monitoring brings new information for the project planning and management and for the risk management.

Purpose The purpose of this paper is to discuss a production planning and control model known as the Lean construction management (LCM) model, which applies a number of visual tools in a systematic way to the planning and control process. The application of the visual tools in this way facilitates the flow of information, thus improving transparency between the interfaces of planning, execution and control. Design/methodology/approach Design Science research is adopted for this investigation, which analyses the original development of the model and reports on its testing and refinement over different types of projects. The research is divided into three parts, each part focussing on a different stage of development and construction project type. Findings The main findings are related to the benefits of visual management in the construction planning and control process, such as maintaining consistency between different planning levels, so that feasible execution plans are created; control becomes more focussed on prevention rather than correction, and creates opportunities for collaborative problem solving. Moreover, the physical display of the visual tools in a discrete planning area on-site encourages a regular exchange between participants on actual work progress as it unfolds, leading to more timely reaction to the problems at hand. Originality/value The problem of a lack of transparency in construction planning and control leads to communication issues on-site, poor process orientation and high levels of waste. LCM improves process transparency by making information related to system-wide processes more readily available to project participants. This enables them to foresee problems in a timely manner and to take necessary measures to resolve them or to adapt the process to current circumstances. The LCM model proposes a new way of applying visual tools and controls systematically to improve transparency in construction planning and control.

Project scheduling is an important task in project management which monitors the project duration, resource utilization and affects the benefit of project for all kinds of project such as construction, IT, renewable energy, product design and manufacturing etc. Among many methods for project management, critical path method (CPM) is one of the better-known planning and control techniques in project scheduling. In this study, CPM-based computerized program was developed together with modeling of step by step calculations of parameters of interest such as earliest starts and finishes, slack and float times of project activities resulting in determination of critical path for the project. One advantage of computer implementation of CPM using MATLAB in this study is that unlike conventional method, it eliminates necessity to conventionally draw network diagram to perform critical path analysis.

Scheduling Technique

The critical path method (CPM) has been useful for project planning, yet its float calculation errors in cases of complex schedules hinders its ability to provide decision supports during project control, namely corrective actions and forensic analysis of schedules. To improve project control, this paper enhances the critical path segments (CPS) scheduling technique and incorporates a rich visualization of all as-built events made by all parties, including work stops, accelerations, and rework. Its improved critical path calculation incorporates the decision variables used at the project control stage such as revised construction methods. It also uses a modified float calculation with forward-pass only to avoid float errors. A case study is used to demonstrate the proposed technique and its benefits for project control. This research has the potential to revolutionize scheduling computations to resolve CPM drawbacks and provide decision support capabilities to help improve project planning and control.
