Question 1: How much ending inventory in pieces is shown in the following value stream?
1621 you can see the amount of ending stock in the Value Shipping Map before the
shipment.
Question 3:
The following administrative process processes customer requests. It
consists of three steps. The cycle time (=processing time per employee
per request) is shown for each step. The takt time is 3 minutes and can be
assumed to be constant (so no fluctuations in the workload), and the
variation in processing times is marginal. You can assume that an
employee can carry out every step independently.
How many employees are ideally needed at least to carry out these three
steps? Consider the concept of resource efficiency.
20 demand/ per hour
Step 1: cycle time: 5 min
Step 2: cycle time: 2 min
Step 3: cycle time: 11 min
The answer is
a. 18
b. 5
c. 6
d. 3
Question 4: What factors will reduce lead time under Little’s Law?
Overcapacity of employees
With more variation in car speeds, more delays quickly occur. Overcapacity
(widening of motorways, extra lanes, special rush lanes) ensures a lower
occupancy rate and therefore more traffic flow.
Question 5:
Avis Company is an international rental company and is located 3 km from
Schiphol airport. An Avis bus runs from its offices to the airport every 2 minutes.
The average travel time (round trip) is 20 minutes. This means from the office to
the airport and back again. How many Avis buses commute to and from the
aiport at least per hour to meet the 2-minute takt time? Use Little’s Law.
Question 6:
A. SIPOC
Is a high-level overview of a process and indicated how the process meets
the needs of customers.
SIPOC is an acronym for Supplier, Input, Process, Output and Customer. A SIPOC
describes the process in broad terms and is a tool for identifying all relevant parts
of the process and therefore for scoping the project. The SIPOC helps to better
understand the process and is a good framework for process improvement. With a
SIPOC you can easily reason from the outside in: customers set requirements for
the output, the desired output sets requirements for the process, the process in
turn sets requirements for the input and this can in turn be translated into
requirements for suppliers .
