All organizations look for to optimize their supply chain , gain more profit and offer a product that meets the quality standards for the customers.
Within organization, we can distinguish those activities that add value and activities that add not value, analize and evaluate the performance of the process , collected information will be useful to propose iniciatives to improve the processes.
For example ,we analyze and evaluate the next process to understand this topic.
1. A company works daily with two shifts , each shift lasts 8 hours , during 5 days per week.
Company has 4 machines. 70% of the time is the availibility for each machine with 90% of efficiency . Calculate the output per week.
Efficiency = Produced Minutes / (Available time - Idle time)
Total Available time per week = 8 hours x 2 shifts x 5 days = 80 hours
Available time per machine = 0.7 * 80 = 56 hours
Output per week = efficiency * Available Time per machine *4 machines = 0.9 * 56 * 4 = 201.6 hours
(Produced Minutes)
2. Projected daily capacity of the company is 100 units, effective daily capacity is 80 units and output per day is 60 units.
a) Calculate the utilization and efficiency
b) Calculate the output for the next month , given the expected efficiency is 90%.
a)
Utilization = Actual Output / Capacity = 60 / 100 = 0.6 x100 = 60 %
Efficiency = Actual Output / Effective Capacity = 60/ 80 = 0.75 x 100 = 75%
b)
Output = effective daily x efficiency = 80 x 0.9 = 72 units per day
3. Calculate the higher production rate of a hair dresser that works 8 hours per day. In average the required time to cut and comb for women and men are 25 minutes and 15 minutes respectively, the time for preparation is 5 minutes per customer. Also is known that 60% of the customers are men.
Item Processing Time %
Man 15 + 5 = 20 x 0.6 = 12
Woman 20 +5 = 30 x 0.4 = 12
Average = 24 minutes per customer
Production Rate (Capacity) = (8 horas x 60 minutos ) / (24 minutes per customer)
Production Rate (Capacity) = 20 customers per day
