Decision Making has been mathematical science nowadays. It formalizes the thinking of decision maker
to make better decision and have transparency in all its aspects. In this paper, the Design on Trade-Off
Strategy were introduced to evaluate the design. Design on Trade-off Strategy is a formal method that
allows the designers to explicitly make trade-off decisions. The project aims to optimize the operations in
one of the fabrication company in the Philippines by designing a production layout that will increase
productivity. After series of observations, this paper identified the factors affecting the low productivity in
the production. The design of the process and production layout was analyzed based on five design
criterions: Economic, Health and Safety, Ergonomics, Environmental and Productivity. The two designs
were evaluated using Trade off Strategies in Engineering Design. This paper recommends the first design
that can contribute for higher productivity.
