The goal of theory of constraints (TOC) is to maximize output, which is achieved byidentifying and managing the critically constrained resources. To manage the constraints, Goldrattproposed five focusing steps (5FS). If we increase constrained output, the output of system will beincreased. In this paper, we focus on step four of the 5FS and use the remained capacity of nonconstraintto elevate t...

A constraint is a limitation or a restriction that poses a threat to the performance and efficiency of a system. This paper presented a tactical review approach to production constraints modeling. It discussed the theory of constraints (TOC) as a thinking process and continuous improvement strategy to curtail constraints in other to constantly increase the performance and efficiency of a system...

Purpose – The primary aim in this paper is to develop and demonstrate a theory of constraints (TOC) model in which constraint resource prevents the throughput of the organization. Design/methodology/approach – In this paper, the authors propose an integrated model by combining Laplace criterion and TOC into a single evaluation model in a multiproduct constraint resource environment. A case stud...

The Theory of Constraints (TOC) is a powerful new management philosophy that recognizes system constraints limit the performance of a system and proposes a set of concepts to manage the constraints. TOC management philosophy (i) suggests the goal of an organization is to make money without violating certain necessary conditions such as customer satisfaction and employee satisfaction and securit...

The purpose of this study is to analyze the role of Strengths, Weakness, Opportunities and Threats (SWOT) analysis and the Theory of Constraint (TOC) approach in the planning and execution of Information Technology (IT) projects. Organizations consider a number of trade-offs during the entire lifecycle of an IT project due to the conflicts between limited resource availability and the timely de...

The aim of this paper is to develop and demonstrate a theory of constraints (TOC) model that utilizes TOPSIS method in estimating the priority of each product in a multiproduct constraint resource environment. The decision model compares four alternatives: Standard cost accounting, Standard Theory-OfConstraints (TOC), LP analysis and our own solution. The numerical results show that the propose...

The successful enterprises deliver products and services in shorter throughput time and turnover inventory as quickly as possible. Three important approaches to achieve these goals are Materials Requirements Planning (MRPI, MRPII), Just-in-Time (JIT), and Theory of Constraints (TOC). TOC seems to be a viable proposition because it does not require costly affair of system change; rather it is si...

We are interested in the problem of time-optimal control of omnidirectional robots with bounded acceleration (TOC-ORBA). While there exist approximate solutions for such robots, and exact solutions with unbounded acceleration, exact solvers to the TOC-ORBA problem have remained elusive until now. In this paper, we present a real-time solver for true time-optimal control of omnidirectional robot...
