Abstract. The relationship between precedence and successor activities is the only factor that determined the project scheduling in the traditional project scheduling management. The critical chain-an elegant solution, on the other hand, takes resource limitations into account and is composed of sections that are dependent on successor relationships and other sections that are dependent on resource constraint. By integrating the existing research findings, it is the objective of this paper to highlight the merits and pitfalls of the CCPM scheduling method, such as the principle for project delays, the critical chain identification; the time buffer setting and project scheduling with limited capacity of a resource. Furthermore, it also presidents the difficulties when implementing the critical chain approach and conclude with a description of our ongoing research direction.

Critical chain scheduling/Buffer management (CCS/BM)—the direct application of the theory of constraints (TOC) to project management—has received much attention in project management literature. There still is controversy over the merits and pitfalls of the CCS/BM methodology. This paper focuses on the fundamental elements of CCS/BM logic and pinpoints some intricacies that are not commonly referred to in the available literature. The authors’ analysis is based on a critical review of the relevant sources and experimentation with both commercial CCS/BM software and an internally developed CCS/BM-based tool.

The concept of green manufacturing has influenced many projects and their progress in manufacturing. In practice, projects in manufacturing should be monitored and controlled from the viewpoint ofgreenality, which is the degree to which a project or an organization has taken into account the sustainability and environmental requirements that influence the target project during its execution. This paper deals critical chain project scheduling, which addresses greenality to encourage the efficient use of resources required for the project. Results of computational simulation demonstrate the applicability and effectiveness of the proposed scheduling method.

The buffer setting and management mechanism in Critical chain method was combined with practical progress vanguard line in this paper. Then the information statistical and analysis methods of project schedule was given, and the methods are applied in project scheduling management of warship scheduled repair. With the application analysis in maintenance project shows that this methods can identify the activity chain which really lead to the lag of project scheduling. This shows that the method was given in this paper presents an applicable value for actual warship scheduled repair project scheduling management. CLC number: U672 Document id code: A

Tourism Supply Chain

Tourism supply chain management has become an important research topic as individual firms no longer compete as isolated entities but rather as supply chains in the tourism industry. Despite the evidence that benefits can be gained to improve profitability, competitiveness, and customer satisfaction, the research on how to manage the tourism supply chain is very limited. This research contributes to the literature by applying the theory of constraints (TOC) with systems thinking to tourism supply chain management. It proposes that the key issue in tourism supply chain management is the coordination of business activities and the TOC with systems thinking can effectively support tourism supply chain coordination of the various links and processes. The article examines the TOC performance measures and the drum–buffer–rope model in the context of tourism management and applies the focusing process of the TOC as a continuous improvement approach for tourism supply chain management. The research findings suggest that, given modifications to the TOC terminology and the principles, the TOC principles can work as an excellent approach to facilitate the tourism supply chain management.

The present study discusses the adequacy of the Critical Chain Project Management Method (CCPM) — also known as the Critical Chain Method — for scheduling projects involving shutdowns on oil platforms, as such projects involve decision-making processes under risk conditions. The CCPM is based on the Theory of Constraints and aims at providing more precise and more clearly focused control instruments than those traditionally used in the Critical Path Method (CPM). The CCPM also indicates the best moments to act and where and how the action should be directed. The hypothesis underlying the research is that the CCPM portrays, more adequately than the CPM, the uncertainty that exists in a platform shutdown. This characteristic also makes it possible to draw up a schedule that is both more realistic and more challenging, as it addresses the goal of causing less interruption of production. On the basis of this hypothesis, the two main questions that oriented the entire investigation were: 1) Is the CCPM suitable for scheduling the shutdown of an offshore oil platform and, 2) What advantages might it have over the traditional methods in use? To answer these questions the authors reviewed the existing bibliography on the topic and made direct on-site observations during an actual shutdown. In addition, interviews were held with a number of specialists in the area using qualitative approaches, namely, semi-structured interviews, focus groups, and action research.

This article analyses the possibilities of the practical utilization of Critical Chain Project Management methodology. Our study analyzed key processes related to the implementation and utilization of such a tool in a concrete company. For this purpose an original program was created. The logic of this program is based on the fundamental principles of the CCPM methodology. The impetus for the design and creation of such a program stemmed from the almost non-existence of such a tool on the Czech market. The theoretical part of the article focuses concisely on the Theory of Constraints and Critical Chain principles, which the conceptual ideas of all algorithms included in the new program come from.The system was used for two years and it enabled the processing of requests significantly faster than before. The evaluation of economical and practical benefits based on real project data demonstrates that after implementation of the Appello system and corresponding rules of usage, project managers completed more tasks in the first year than in the previous two years in which the CCPM was not applied and nearly 85% of planned requests were either on time or delayed up to 30 days in comparison with the amount of work from the preceding two years.Currently, a significant number of project oriented companies are looking for competitive advantages which, allow for the mastering of the largest number of projects that have a delivery time specified within agreed time frames. The use of our system or similar ones designed according to CCMP rules fully ensures the fulfilment of such requirements.

Project Delay

Project scheduling is the next step once project planning is completed. This requires knowledge and the depth of the activities, the dependencies between activities and, duration of the activities. Creating and designing a realistic project schedule is the biggest challenges a project manager faces. There are some common problems that can be impact towards project delay or performance: Assigning Resource or Resource Constraint, Managing the Unknown or Managing Change and Estimating Task Duration. These 3 factors and causes are contributing to project scheduling problem. The impact of resource constraint causes towards be impact towards project delay or performance.  To achieve this goal, the survey has been conducted. Finally, the results of the surveys are presented in order to see which commons problems are the most happening and really effected project scheduling.
