PART 1. Using IDEF0 methodology, draw a complete model to specify an organization of your choice
(industrial, service, or public). This model should specify the organization down to its 2nd level of
decomposition (i.e., include function blocks at the Axx level), taking into consideration of all the aspects
such as outlined below:
Follow strictly the cross-checking steps to ensure the integrity of your model:
1. Specify and Cross-Check a function block: for each of the Inputs, cross-check for its related
Output(s); for each of the Outputs, cross-check for its related Input(s); for each of the Mechanism
and Control, check what it is used for.
2. Decompose, if needed, to 3-5 next level functions. For each of these sub-level functions:
x Carry out the Specify and Cross-Check as outlined in (1)
x Establish relationships amongst these functions through flow of Inputs,
Outputs, Controls and Mechanisms
x Cross-Check Integrity of Decomposition: lower-level definition should
represent EXACTLY its higher level function.
3. Repeat step 2 until the required level of detail is reached.
You should provide a textual description of the overall system/organization of concern, as well as for each
of the function blocks presented in the model.
PART 2. From your IDEF model of the organization, pick up two related functions. Draw an ActivityCycle-Diagram
to illustrate how the dynamic interaction takes place.
PART 3. Explain, with flowchart if necessary, how simulation process can be logically carried out to
estimate the system performance in terms of average lead time, and/or average resources utilization. Then,
for the ACD model of Part 2:
x Assign time elements involved (such the average and distribution times of arrival, and
machining/process/service times)
x Carry out a simulation, physically, and estimate the values related to system performance such as
the mean throughput and/or the average waiting times.
