Disease-symptom relationships are of primary importance for biomedical informatics, but databases that catalog them are incomplete in comparison with the state of the art available in the scientific literature. We propose in this paper a novel method for automatically extracting disease-symptom relationships from text, called SPARE (standing for Syntactic PAttern for Relationship Extraction). T...

We propose a method that can be used when deciding on how to maintain capital goods, given a product design and the layout of a repair network. Capital goods are physical systems that are used to produce products or services. They are expensive and technically complex and have high downtime costs. Examples are manufacturing equipment, defense systems, and medical devices. Due to the high downti...

Mechanical pressure clamps are examples of innovative tools commonly used in the oil and gas industry for arresting leaks from damaged oil and gas pipelines. However, if leaks result from pipeline rupture, clamps are not usually recommended. It is therefore obvious that inspection of the leaking pipeline is very crucial in deciding the strategy for repair. For subsea pipelines where underwater ...

In this paper we analyze the interval availability of a two-echelon, multi-item spare part inventory system. We consider a scenario inspired by a situation that we encountered at Thales Netherlands, a manufacturer of naval sensors and naval command and control systems. Modeling the complete system as a Markov chain we analyze the interval availability. We compute in closed and exact form the ex...

In many industrial sectors, firms are dealing with a demand which is more and more uncertain often due to the supply chain structure. One of the most critical effects of demand uncertainty is the simultaneous increase of inventories and decrease of customer service. This work describes an integrated system for managing inventories in a multi-echelon spare parts supply chain, in which customers ...

However, there is a lot of capital and plenty of manpower in the auto spare part industry, the enterprises and supply chains of this industry do not perform well in our country. This research models a three-level supply chain with multiple manufacturers, distribution centers and retailers, to minimize the total cost by taking into account various disruptions. The database of two active car spar...

The spare part inventory is an important section that must be managed and controlled in the company, primarily because this supports provision of parts for manufacturing process. An excellent management system matches records SAP warehouse actual physical evidence. problem faced by consumer goods company was difference between recording evidence non-consumable goods. By implementing improvement...

The results obtained from the RCS worksheet show that there is 1 unit of high critical category component, 10 units medium component and 4 low component. Calculation requirements for next 12 months using Poisson process total requirement spare parts to be able meet 95% availability v-belt mixers 7 (12 = 21 units), hydraulic rubber requires months=12 vibrating system 2 6 units). Order size costs...
