Przedstawiono krótkie omówienie metody, zwanej CC/BM (critical chain scheduling and buffer management) lub CCPM (critical chain construction project). Podkreślono, że nie jest ona powszechnie znana i stosowana w praktyce w Polsce. Przedstawiono przykład wykorzystania tej metody do harmonogramowania przedsięwzięcia budowlanego. Przytoczono krytyczną analizę tej metody w odniesieniu do warunków realizacji przedsięwzięć budowlanych. Zaprezentowano koncepcję udoskonalenia metody harmonogramowania łańcucha zadań krytycznych.

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.

Performing the Critical Chain Scheduling (CCS) and Buffer Management (BM) in project management has recently risen as one of the most popular project management approaches. The critical Chain Scheduling (CCS) approach is replacing the traditional scheduling method to reduce the uncertainty associated with time schedules. The research highlights the importance of critical chain scheduling in project execution by investigating using buffers in the critical paths and the feeding baths in project management using a real case study. The case study was studied by analyzing the schedule provided and then implementing CCS and BM using four different methods. The methods are cut and paste (C&PM), the root square method (RSEM), the Adaptive procedure with resource tightness, and the Adaptive procedure with network density (APND). The buffer size obtained for each method was determined. From the result got, for project buffer in adaptive approach with network density method yields a larger buffer size compared to the adaptive procedure with resource tightness method. While for feeding buffer also show that APND resulted in a larger buffer size than APRT. Finally, the proposed buffer size was investigated and simulated using the What if approach.

Activity Attributes

The direct application of the Theory of Constraints (TOC) to construction engineering, known as Critical Chain Management and Buffer Management (CCM/BM), has recently emerged as one of the most popular approaches to schedule management. However, the existing buffer setting techniques have less aken the activity attributes into account. In this paper, we introduce the concept of structure entropy to reflect the complexity of schedule network of construction project and propose a novel method for buffer sizing based on an in-depth analysis of activity attributes. After simulation test and comparison with classical methods, the proposed method is proved to have better accuracy and effectiveness.
