In many cases, supermarkets are founded on rental of already built property and in this case, the space is accepted as is. It is imperative in this case that the supermarket be designed to achieve multiple objectives such as ease of roaming, display area, special display areas etc. It is important for any store to have a good design, because it will be reflected on the customer’s satisfaction, which in turn will increase sales and will ease customer flow. Several possible ready-made designs are available in the literature such as Grid, loop, and mixed. When implemented on the current space limitations, they can have different achievement for the objectives of the design. Analytical Hierarchy process (AHP) represents a suitable technique for comparing these designs and reaching the final layout design selection. AHP layout selection is applied to a local supermarket and different layouts were generated. The design objectives are then evaluated for each of the layouts. It was concluded initially there is variability in the objectives achieved by the different designs, and a suitable multi-objective technique is required to select the final design. AHP is used to determine which of the designs was the most suitable through multiple comparison and consistency check. The results showed that the grid design was the most suitable for the current case study.

Life cycle costing (LCC) is a methodology used first time by the Department of Defense of United State, it’s an economic calculation of all costs propagated during the life span of any technical system. For Renewable Energy (RE) systems, LCC is a good methodology, which shows the cost-effectiveness of using RE as an alternative source compared to conventional power generations. A LCC model was introduced for PV generation system. Data collection was done through four different cost data sources. The results shows that the average module price is $0.56/Wp and the capital investment cost is $1.184/Wp. For a 20 years PV project life-time, the operation and maintenance cost forms 27% of the total LCC of the system.

Cellular manufacturing is an important tool for manufacturing firms which leads to better productivity, focused and specialized manufacturing process. To utilize this important tool, the machines have to be grouped into cells. This work is related to using cellular manufacturing in a pharmaceutical factory with alternative routing. This adds more choices in the decision making process and presses for a better tool to make optimal selection. Several objectives may be considered to improve the productivity objectives such as the total number of exits and planning and scheduling robustness related objectives like bottleneck utilization and load balance between and within the alternative routes. Analytical hierarchical process (AHP) is used as a multi-objective decision making process to evaluate the best scenario amongst generated using simulation as a tool for modeling and evaluating the output for each scenario. Three customer case studies were considered with different preferences and the AHP evaluated the best scenario to fit these preferences. The best scenario can vary from one customer preferences to another but for the current system it turned out to be the same choice.

Life Cycle Costing (LCC) is a methodology used first time by the Department of Defense of United State, it’s an economic calculation of all costs propagated during the life span of any technical system. For Renewable Energy (RE) systems, LCC is a good methodology, which shows the cost-effectiveness of using RE as an alternative source compared to conventional power generations. A LCC model was introduced for Wind generation system. Data collection was done through four different cost data sources. The results shows that the capital investment cost is $1.968/W. For a 20 years PV project life-time, the operation and maintenance cost forms 19% of the total LCC of the system.
