Résumé en anglais This paper deals with formal modelling of Petri nets including shared resources. These phenomena appear widely in the production management context, for the modelling of manufacturing cells. But, they usually cannot be formally represented in dioid algebraic structures based on sets of scalars. In this paper, we design a method to describe such a phenomenon in a dioid of inter...

Lean construction has recently gained momentum in England’s highways construction supply chain. The literature indicates that the current view to Visual Management (VM) within those lean implementations is limited to some VM tools. This paper explores the condition of VM, which is a fundamental sensory information management strategy in the lean production system, in the highways sector in Engl...

Erratic rainfall and rapidly changing world markets have led to volatile stock prices and variable returns to beef producers in recent years. Many producers have subsequently reviewed their choice of enterprise or management system and so an examination of long-term markets is useful when contemplating or advising on possible changes. A comparison of selected beef enterprise gross margins from ...

39.2 ± 2.2 kg) were greater (P < 0.01) with AL feeders than with HF feeders, respectively. Number of pigs weaned did not differ (P > 0.05, 9.7 ± 0.1). The AL sows tended to have greater (P = 0.07) wt gains during lactation (12.2 ± 3.1 vs. 8.2 ± 3.2 kg, AL and HF, respectively). Backfat change during lactation and wean-to-estrus interval did not differ (P >0.05). Sows with AL feeders wasted less...

Skill management in industry is one of the most important factors required in order to obtain optimal performance of the production system. This is of particular importance in the field of maintenance where the different practical knowledge or skills are the working tools used. We address, in this paper, both the assignment and scheduling problems that may be found in a maintenance service. Eac...

Metadata is essential for understanding information stored in data warehouses. It helps increase levels of adoption and usage of data warehouse data by knowledge workers and decision makers. A metadata model is important to the implementation of a data warehouse; the lack of a metadata model can lead to quality concerns about the data warehouse. A highly successful data warehouse implementation...

To identify the factors contributing to the farmers’ attitude towards Integrated Pest Management (IPM) practices in rice cultivation, 158 family heads of the Farmers Field Schools (FFSs) at Godagari Upzila under Rajshahi District were chosen at random to constitute the subjects of the study. Data were collected from 5 September, 2006 to 28 January, 2007. Twenty four selected characteristics of ...

The development, design and selection of subsea petroleum production equipment and facilities are critical activities, as the decisions made will impact the success and profitability of the project. Technical, economic and government regulations are some of the factors that need to be evaluated in order to contract subsea services and procurement activities. Pre-studies need to be conducted to ...
