Operational systems consist of components that deteriorate and eventually fail. Upon failure, components are either repaired or replaced. Cheap and critical components are usually replaced, while expensive and non-critical components are repaired several times before complete replacement. In this research work, repairable systems undergoing imperfect repair are examined. In this type of repair,...

Service processes, for example in transportation, telecommunications or the health sector, are the backbone of today's economies. Conceptual models of service processes enable operational analysis that supports, e.g., resource provisioning or delay prediction. In the presence of event logs containing recorded traces of process execution, such operational models can be mined automatically. In th...

in this article, a numerical method based on  improvement of block-pulse functions (ibpfs) is discussed for solving the system of linear volterra and fredholm integral equations. by using ibpfs and their operational matrix of integration, such systems can be reduced to a linear system of algebraic equations. an efficient error estimation and associated theorems for the proposed method are also ...

Purpose Collaboration and operational capabilities are two strengths for managing supply chains to achieve performance. In this context, study aims analyze the mediating effect of on relationship between collaborative chain management Design/methodology/approach The design consisted a theoretical framework estimate mediation paths by latent variable structural modeling methods. A survey 138 res...

the main objectives of a profitable organization are its survival, excellence and finally its prosperity. the organizational prosperity depends on performance based on dimensions called abilities and motivations of the organizations. therefore, the organizations need to have contingency integration between those two dimensions. in the past two decades, we have seen different views and models de...

learning rapidly and competently has become a pre-eminent strategy for improving organizational performance in the new knowledge era. improving dynamic learning capability is an exclusive strategy for corporate success in construction industry. thus engineering design firms should implement ol to accomplish a state of readiness for change and develop a competence to respond and identify future ...
