Lean manufacturing emphasizes the elimination of waste and the smooth flow of value‑adding activities. Accurate capacity planning ensures that the production system can meet customer demand without over‑burdening resources, which is a core principle of lean.
The required number of machines (or workstations) is driven by three key variables: the forecasted demand for the product, the time each unit takes to be processed (cycle time), and the effective operating time each machine can contribute during the planning horizon.
By converting all time measures to a common unit (minutes) and accounting for the desired utilization rate, planners can calculate the minimum machine count that satisfies demand while preserving flexibility for continuous improvement.
D = demand (units per period)
CT = cycle time (minutes per unit)
O = operating time per machine (minutes per period)
U = utilization (decimal)
