Problem 1: Sola Communications has redesigned one of its core business processes. Processing times are not expected to vary significantly, so the management wants to use the line-balancing approach to assign activities to workstations. The process has 11 activities, and the market demand is to process 4 jobs per 400-minute working day. Table 2 shows the standard time and the immediate predecessors for each activity in the process.

First, construct a precedence diagram to help you answer the questions.

Calculate the cycle time corresponding to a market demand of 4 jobs per day (required cycle time).

A) 100

B) 200

C) 300

D) 400

First, construct a precedence diagram to help you answer the questions.

What is the actual minimum number of workstations?

A) 5

B) 4

C) 3

D) 2

Problem 3: Use the longest activity time rule as the primary rule to balance the line.

What is the efficiency of the line?

A) 86%

B) 79%

C) 61%

D) 925
