This paper presents a new model of two-echelon periodic supply vessel planning problem with time windows mix of facility location (PSVPTWMFL-2E) in an offshore oil and gas industry. The new mixed-integer nonlinear programming (MINLP) modelconsists ofa fleet composition problem and a location-routing problem (LRP). The aim of the model is to determine the size and type of large vessels in the fi...

Mathematical models have been used in many areas of supply chain management. In this paper, we present a mixed-integer non-linear programing (MINLP) model to solve a multi-period, closed-loop supply chains (CLSCs) with two echelons consist of producers and customers. In order to satisfy the demands, the producers are be able to order for materials in the beginning of each period for one or more...

The upper Echelons Theory reiterates the importance of top management in an organization and recognizes that mangers make decisions grow entity. Before establishment this theory, premise was larger firms which drive high amounts income, are capable running themselves without failure. Although Organizations command large income deemed to be successful echelons theory holds these entities cannot ...

Drawing on the notion of “faultlines” and upper echelons perspective, we argue that gender faultline strength a board directors is negatively related to strategic change. More interestingly, while relates change under low levels environmental complexity, dynamism, munificence, it positively when munificence are at high levels. The analyses panel data 5781 firm-year observations 1171 Chinese fir...

The unprecedented COVID-19 outbreak strengthened the critical manifestation of rapid development vs. survival for pharmaceutical companies, deploying strategic conduct worldwide. This study therefore explores endogenous relationship among companies’ manufacturing strategy and their performance indicators within ambit creating a long-lasting competitive advantage in turbulent times. Very often, ...

This study examines the relationship between religiosity and Islamic debt financing based on Malaysian non-financial listed firms from 2012 to 2018. We find that Muslim CEOs allocate more in their compared non-Muslim CEOs, which support upper echelons theory. However, we sociological pressure Stakeholders display no significant effect financing. Interestingly, further will incline matter whethe...

The utilization of negative pressure for medicinal purposes dates back to 600 bc. The U.S. military has been engaged in continuous overseas combat operations since 2001. Negative-pressure wound therapy has been in use in the treatment of casualties from these operations since 2004. It represents a new standard of practice in combat wound care; it promotes granulation tissue formation and create...

Given a product design and a repair network for capital goods, a level of repair analysis determines for each component in the product (1) whether it should be discarded or repaired upon failure and (2) at which location in the repair network to do this. In this paper, we show how the problem can be modelled as a minimum cost flow problem with side constraints. Advantages are that (1) solving o...
