This paper presents an alternative model to deal with the problem of optimal energy consumption minimization of non-isothermal systems with variable inlet and outlet temperatures. The model is based on an implicit temperature ordering and the "transshipment model" proposed by Papoulias & Grossmann (1983). It is supplemented with a set of logical relationships related to the relative position of...

As competition from emerging economies such as China and India puts pressure on global supply chains and as new constraints emerge, it presents opportunities for approaches such as game theory for solving the transshipment problem. In this paper we use the well-known Shapley value concept from cooperative game theory as an approach to solve the transshipment problem for maintaining stable condi...

We consider a supply chain, which consists of several retailers and one supplier. The retailers, who possibly differ in their cost and demand parameters, may be coordinated through replenishment strategies and transshipments, that is, movement of a product among the locations at the same echelon level. We prove that in order to minimize the expected long-run average cost for this system, an opt...

Generally, the inventory routing problem occurs in a supply chain where customers consider the supplier responsible for inventory replenishment. In this situation, the supplier finds the answer to questions regarding the time and quantity of delivery to the customer as well as the sequence of customers in the routes. Considering the effect of production decisions on answering these questions, t...

We show that no difference between PL isotopy and TOP isotopy (as equivalence relations on PL links in S 3) can be detected by finite type invariants. Next, let L be a link with components K 1 ,. .. , Km, and let Q L denote either the Conway polynomial, or a certain exponential parametrization of the HOMFLY or the Kauffman two-variable polynomial, or any of certain 2 m−1 polynomials, in totalit...

In this paper, we describe linguistically sophisticated tools for the automatic annotation and navigation of on-line documents. Creation of these tools relies on research into finite-state technologies for the design and development of lexicallyintensive semantic indexing, shallow semantic understanding, and content abstraction techniques for texts. These tools utilize robust language processin...

A water jet machining is an industrial tool capable of cutting a wide variety of materials using a very high-pressure jet of water, or a mixture of water and an abrasive substance. This paper addresses the concept of the Intelligent knowledge base system (IKBS) for optimization of product design and manufacturing process for water jet machining in computer based concurrent engineering environme...

In this study, a two echelons supply chain system in which a supplier is producing perishable product and distribute it to multiple customers is considered. By allowing lateral transshipment mechanism, it is also possible to deliver products to some customers in some periods in bulk, then customers using their own vehicle to transship goods between each other seeking further reduction in the ov...

The world-wide crisis caused by the Coronavirus disease 2019 (COVID-19) pandemic had a significant impact on global economy functioning and sustainable development of supply chains. changes also affected seaports being key links maritime purpose research study described in this article was to identify sources kinds disruptions observed various chains as result COVID-19 their operations types se...
