Purpose: The theory of constraints (TOC) methodology and its drum-buffer-rope (DBR) production planning and control system are well suited to managing production plants in complex environments. The objective of this study was to design an evolution of the systematic process for implementing the third step of the TOC methodology in make-to-order env...

The research work conducted by Orue et al. [1] aims to analyze the impact of protective capacity on the application of the third step of the drum-buffer-rope methodology of the theory of constraints (subordinate everything to the bottleneck) in make-to-order environments. To analyze the impact of protective capacity, a discrete event simulation is...

This study uses simulation to analyse the impact of protective capacity in the implementation of the step 3 of the theory of constraints (TOC) methodology in make-to-order (MTO) environments. The results suggest that at different levels of variability, different levels of protective capacity are needed to keep a system stable and meet the bottlenec...

Several authors agree on the importance of integrating sales and operations (S & OP) when it comes to improving the management of organisations. Thus, the relationship between S & OP can be critical from a competitive point of view, and therefore strategic. However, most of the literature on this topic focuses on the field of repetitive manufacturi...

Purpose: The theory of constraints (TOC) drum-buffer-rope methodology is appropriate when managing a production plant in complex environments, such as make-to-order (MTO) scenarios. However, some difficulties have been detected in implementing this methodology in such changing environments. This case study analyses a MTO company to identify the key...

p class="TtuloAbstract">Since the creation of the demand-driven material requirement planning (DDMRP) model, numerous studies have analysed the methodology’s significant impact on different organisations. Several successful cases and research studies into DDMRP have demonstrated that the methodology is beneficial to organisations because it increas...

The present study describes a methodology to apply the DOE (Design of Experiment) techniques. To show its application, a simple case was prepared that can be used as a training in industrial environments. In this case, fractional factorial designs were applied and the effects and interactions that influence the analyzed response were determined. Th...
