IMSE 2030 - Fundamentals of Systems Design and Analysis – Assignment 2
Complete below and produce ONE report to include all parts.
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 those identified in the FIVE categories in a typical industrial system.
Follow strictly the cross-checking steps to ensure the integrity of your model:
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.
Decompose, if needed, to 3-5 next level functions. For each of these sub-level functions:
Carry out the Specify and Cross-Check as outlined in (1)
Establish relationships amongst these functions through flow of Inputs,
Outputs, Controls and Mechanisms
Cross-Check Integrity of Decomposition: lower-level definition should
represent EXACTLY its higher level function.
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:
Assign time elements involved (such the average and distribution times of arrival, and
Carry out a simulation, physically, and estimate the values related to system performance such as
the mean throughput and/or the average waiting times.
Length and Structure: No more than 20 pages (1.5 spacing and including figures). Please
properly “section” your report, so that it follows the format of a typical technical report.
Date of submission: To be decided with class.
