This paper introduces a design for agile manufacturing workcells intended for light mechanical assembly of products made from similar components (i.e. parts families). We define agile manufacturing as the ability to accomplish rapid changeover from the assembly of one product to the assembly of another product. Rapid hardware changeover is made possible through the use of robots, flexible part ...

Abstract Introduction Junior doctor changeover has been perceived as a period of increased risk to patients. However, there is paucity contemporary evidence into this ‘Changeover Effect’. The aim study was evaluate the presence an adverse patient effect during periods junior changeover. Method Data were requested on all patients aged 18 years or older admitted acutely under General Surgery in N...

changeover in the new Member States. In doing so, it draws on the experiences of those 12 countries that have already introduced the single European currency, with a specific focus on the case of Austria. This experience can be a useful signpost for new Member States, even though their starting conditions differ because the euro already exists and most of the countries in question are on a catc...

This paper examines the in ationary consequences of a currency changeover in the catering market. Empirical evidence from the Michelin Red Guide shows that: i) di erently from restaurants in non-euro countries, restaurants in the euro area experienced abnormal price increases just after the changeover, ii) among restaurants in the euro area, tourist restaurants are responsible for most of the a...

We are given a digraph G = (N, A), where each arc is colored with one among k given colors. We look for a spanning arborescence T of G rooted at a given node and having minimum changeover cost. We call this the Minimum Changeover Cost Arborescence problem. To the authors’ knowledge, it is a new problem. The concept of changeover costs is similar to the one, already considered in the literature,...

We consider the discrete lot-sizing and scheduling problem with sequence-dependent changeover costs and times and propose to solve it as a mixed-integer program using a commercial solver. Our approach is based on the extension of an existing tight formulation for the case without changeover times. Computational results con rm the bene ts of the proposed solution procedure.

Operations management is a key aspect in any manufacturing business. Optimising the of operations allows improvement productivity and efficiency industrial activities. To achieve this, reducing waste from processes and, therefore, implementing lean-manufacturing principles, key. This article presents case study to reduce changeover at ready-meal manufacturer based South Yorkshire, UK. We identi...
