And the work pieces moved from one department to the other as follows

Principles Of Operations Management, Chapter 9, Problem 2P , additional homework tip  2

Calculation of cost of plan A layout:

Calculate the total weekly material handling cost, MH cost using the formula

MHcost=i=1nj=1nxij×Cij (1)

where   n= total number of departments

i,j = individual departments

xij= number of loads moved from department i to department j

Cij= cost to move an item from department i to department j

Substitute into the equation (1), the various values to obtain

MtoD=20×600×$0.5=$6,000MtoF=12×1,800×$0.5=$10,800MtoP=8×200×$0.5=$800

DtoF=400×6×$0.5=$1,200DtoP=200×10×$0.5=$1,000FtoP=4×1,800×$0.5=$3,600

Add all the costs to obtain the total material handling costs $23,400_ .

Hence, the cost of plan A layout is $23,400.

Calculate the total weekly material handling cost, MH cost using the formula

MHcost=i=1nj=1nxij×Cij (2)

where   n= total number of departments

i,j = individual departments

xij= number of loads moved from department i to department j

Cij= cost to move an item from department i to department j

Substitute in equation (2), the various values to obtain

MtoD=20×600×$0.5=$6,000MtoF=8×1,800×$0.5=$7,200MtoP=12×200×$0.5=$1,200

DtoF=400×10×$0.5=$2,000DtoP=200×6×$0.5=$600FtoP=4×1,800×$0.5=$3,600

Add all the costs to obtain the total material handling costs $20,600_

Hence, the cost of the layout is $20,600.
