Feasibility Studies Flashcards
Feasibility studies
The use of various methods to assess the practicality of a project
Lean manufacturing
A strategy pioneered by Toyota, involving reducing waste in manufacture such as time, materials or idle machines
Computer modelling in production planning and especially in lean manufacture
Simulation and planning of the assembly line, workstations and cells etc
Predictions of delay in production to help plan buffer zones for temporary storage of partially completed work whilst slower tasks are completed
Cycle time for manufacturing processes is calculated
Calculation of Takt time
Buffer zone
A production line temporary storage area for partially completed products
Cycle time and Takt time
Cycle time - the time taken to complete a manufacturing process
Takt time - the maximum amount of time to manufacture a product to meet consumer demand. Calculated by:
Production time / customer demand
Feasibility studies and Costings
Spreadsheets are used to calculate the two categories of costs:
1 - direct costs such as materials and labour
2 - indirect costs such as factory lighting, rent and salaries
Factoring in unit sale price allows assessment of potential profit and feasibility
Sophisticated computer modelling is used for more complex aspects of production e.g. Injection moulding:
Initial mould cost
Size of moulding, materials and cycle time, including cooling
Number of units to be produced
Feasibility computer modelling in design
Computer modelling an be used to test feasibility of designs:
Arrangement and interaction of components - e.g. Kitchen layout ergonomics
Assembly and disassembly procedure - e.g. Development of jet engines
