Theme Facility Planning Capacity Planning Efficiency and Utilization Importance of Capacity Decisions Facility Layout Factors affecting layout Types of layouts Service Location Strategies
Time Aggregated output Estimate of current capacity Forecast demand Measure aggregate capacity and demand Identify the alternative capacity plans Choose the most appropriate capacity plan
CAPACITY : the capacity of an operation is the maximum level of value-added activity over a period of time that the process can achieve under normal operating conditions. FACILITY: Facilities management involves the management and development of the workplace to integrate people and their work in the operation to achieve the objectives of the organization.
HOW MUCH LONG RANGE CAPACITY NEEDED WHEN MORE CAPACITY IS NEEDED WHERE FACILITY SHOULD BE LOCATED HOW FACILITY SHOULD BE ARRANGED
approach for determining the overall capacity level of capital intensive resources, including facilities, equipment, and overall labor force size.
Design capacity Maximum obtainable output Effective capacity, expected variations Maximum capacity subject to planned and expected variations such as maintenance, coffee breaks, scheduling conflicts. Actual output, unexpected variations and demand Rate of output actually achieved--cannot exceed effective capacity. It is subject to random disruptions: machine break down, absenteeism, material shortages and most importantly the demand. 9
10 Actual output Efficiency = Effective capacity Actual output Utilization = Design capacity
Alternative 1: Purchase one large facility, requiring one large initial investment Alternative 2: Add capacity incrementally in smaller chunks as needed

A facility layout is an arrangement of everything needed for production of goods or delivery of services. A facility is an entity that facilitates the performance of any job. It may be a machine tool, a work centre, a manufacturing cell, a machine shop, a department, a warehouse, etc

Process layout Product layout Fixed- position layout
Car 1 Car 2 Car 3 Process layouts, also known as functional layouts, group similar activities together in departments or work centers according to the process or function they perform. The specialized machines and equipments are grouped together one after then other in order of sequence required in production process convyer
Product layouts, better known as assembly lines, arrange activities in a line according to the sequence of operations that need to be performed to assemble a particular product. Each product or has its own "line" specifically designed to meet its requirements. The flow of work is orderly and efficient, moving from one workstation to another down the assembly line until a finished product comes off the end of the line.
Fixed-position layouts are typical of projects in which the product produced is too fragile, bulky, or heavy to move. Ships, houses, and aircraft are examples. In this layout, the product remains stationary for the entire manufacturing cycle.
Maximize the volume of business and revenue: Purchasing power of the customer-drawing area. Service and image compatibility with the customer- drawing area. Competition in the area. Quality of the competition. Uniqueness of the firm’s and competitor’s locations. Physical qualities of facilities and neighboring businesses. Operating policies of the firm. Quality of management.
