Problem Statement

Studying the current process and suggesting improvements to make it more organized and effective. They are also establishing one more plant for similar products, so by studying process from here

making a process effective layout for the upcoming plant.

ObjectiveThe objectives of this project were as follows:

To study and analyse the manufacturing process of collars, belts, whips, etc. To suggest improvements in the current process To suggest a new layout for the Zorbas new plant

Physical Plant Layout

Plant layout planning includes decisions regarding the physical allocation of the economic

activity centers in a facility. A facility layout is an arrangement of everything needed for

production of goods or delivery of services.

An economic activity center is any entity occupying space.The objective of plant layout planning is a more effective work flow at the facility, allowing

workers and equipment being more productive.

To make a decision about layout planning, 4 different questions must have an answer:

1. Which centers do we have to consider?2. How much space and capacity is required for each center?

If there is not enough space, productivity may be reduced.

Too much space is expensive and may also reduce productivity.

3. How must the space be configured at each center?Space quantity, shape and the elements of the work center are related to each other.

4. Where should each center be located at within the facility?The allocation of the different centers may affect productivity.

Factors affecting plant layout

Materials

The layout of the productive equipment will depend on the characteristics of the product

to be managed at the facility, as well as the different parts and materials to work on.

Labor

Labor has to be organized in the production .

Material Handling

Material handling does not add value to the product; its just waste.

The building

If it has been already selected, its characteristics will be a constraint at the moment ofdesigning the layout, which is different if the building has to be built.

Future changes

One of the main objectives of plant layout is flexibility.

Its important to forecast the future changes to avoid having an inefficient plant layout in

a short term.

TYPES OF PLANT LAYOUT

The production process normally determines the type of plant layout to be applied to the facility:

Product oriented plant layout

Machinery and Materials are placed following the product path. This type of plant layout is useful when the production process is organized in a

continuous or repetitive way.

Advantages:

Reduced material handling activities. Work In Process almost eliminated. Minimum manufacturing time. Tasks simplification.


7/20

6

Disadvantages:

No flexibility in the production process. Low flexibility in the manufacturing times. High capital investment. Monotonous work

Process oriented plant layout (Functional Layout)

This type of plant layout is useful when the production process is organized in batches.

Personnel and equipment to perform the same function are allocated in the same area.

Cellular layout

Work cells: Group of equipment and workers that perform a sequence of operations over

multiple units of an item or family of items.

Looks for the advantages of product and process layouts:

Product oriented layout: Efficiency Process oriented layout: Flexibility

Current Layout Design

Processes:

A: Leather Cutting: Here the skin or the leather is cut in order to start the process of collar manufacture.

This is done on 2nd floor. The time taken for this process is 1.5+1 i.e. 2.5 minutes. The extra one minute is

taken to compensate for the time lost in taking the leather ( i.e. the skin used) to the second floor.

B: Adhesive Applying: Here adhesive is applied to the cut leather from process A in order to fold it and

give it the desired shape. Time taken for this process is 0.5 minutes.

C: Folding: Here the leather is folded and shaped into a collar. Time taken for this process is 1.2 minutes.

D: Roughing surface: Here the surface of leather is roughened using a machine so that it might not create

further problems while sticking. Time taken for this process is 1+1 i.e. 2 minutes. The extra time is added

because this process is being done on the terrace.

E: Punching: This is the stage where the collar is punched in order to attach beads and other such

decorative items to it (done by hand). Time taken for this process is 1+1.5 i.e. 2.5 minutes. Extra time is

added to account for the time taken to bring it back to the previous floor.

F: Bead Attachment: In this process, beads are attached to the collar by hand. Time taken for this process

is 1 minute.

G: Tape sticking: To support the beads and the collar, tape is stuck to the collar. Time taken for this

process is 0.5 minutes.

H: Edge Shaping: The edges of the collar are given a proper shape by scaling. Time taken for this process

is 1.5 minutes.

I: Thick Tape Sticking: A thick tape is stuck to the collar at this stage in order to provide it stiffness and

avoid damage to the stitching done later on. Time taken for this process 0.5 minutes

J: Backside leather sticking: Sticking leather to the backside of the collar. At this stage adhesive is applied

to the backside of the leather and then a second piece of leather is stuck in order to provide it more

strength. Time taken for this process is 0.8 minutes.

K: Collar stitching: This is the process in which the stuck leather at the back of the collar is stitched to

provide it even more strength (by hand). Time taken for this process is 1+1.5 i.e.2.5 minutes. Extra time is

taken into consideration as this process is done on the ground floor

L: In this process, buckle is stitched to the collar by hand. Time taken for this process is 1+3 i.e. 4

minutes.This process is done again on the 2nd

floor, hence time is added.

M: Holes are punched to the collar using a pattern. Time taken for this process is 1 minute.

N: Final Finishing: In this process, final touch is given by removing the threads and Time taken for this

process is 1 minute.

O: Packaging: this is the final process where the final sorting of collar and the packaging is done in order

to send the product for final shipping. Time taken for this process is 1.5+1.5 minutes. This process is done

in the basement.

Total flow time = 4.2 + 2 + 3.5 + 3.6 + 2.5 + 6 + 3 = 24.8 min

Estimated cycle time = No. Of working hours * 60 / Total production per day of collars

Here we have

No. Of working hours = 8 hrs. ( as approximated by zorba)

Total production per day of collars = 100

So,

Estimated cycle time = 8*60/ 100 = 4.8 min

Now,

Efficiency of the current layout = Total flow time / No. Of workstations * estimated cycle time

= 24.8/(8*4.8)

= 64.6 %

Assembly Line Diagram in New Layout

Changes In New Layout:

We have moved apparel section from Ist floor to 2nd floor to keep it separate since it is notrelated to collar making process.

We have moved process D i.e. Rouging process from terrace to 1st floor to reduce the time inshifting unfinished goods to and fro from 2

ndfloor to terrace.

We have moved collar making process (A, B, C and E, F, G, H, I,J) altogether to 1st floor toreduce the timing of moving inventory from basement to 2nd floor.

Processes L, M,N are moved from 2 nd floor to ground floor and this will make the space ofkeeping Rough surface making machine which is shifted from terrace to 1 st floor. And utilizing

the free space available in ground floor where just whip making process is going on.

There are no change in packaging and inventory keeping since it is little a private materials ofZorba which they want to keep it secured.

Total flow time = 4.7 + 4.8 + 3.5 + 4 + 3 = 20 min

Estimated cycle time = No. Of working hours * 60 / Total production per day of collars

Here we have

No. Of working hours = 8 hrs. (as approximated by Zorba)

Total production per day of collars = 100

So,

Estimated cycle time = 8*60/ 100 = 4.8 min

Now,

Efficiency of the new layout = Total flow time / No. Of workstations * estimated cycle time

= 20/(5*4.8)

= 83.33 %

Hence, new layout has more efficiency as compared to current layout.

Apparel Precedence Diagram

The entire apparel stitching process is performed on the first floor right from cutting of cloth uptil final

packaging. This floor also houses some of the various accessories that Zorba International provides. Few

examples are dog shoes, raincoats, jackets, ties, bathrobes, towels , etc.

Individual Processes

1) CuttingIn this process the cloth for apparel is cut into a proper shape using a pattern with accurate

dimensions. This process is done by hand using scissors. This process takes around 10 min

2) StitchingThe stitching process comes next. Here the entire cloth piece which was previously cut is

stitched into nice apparel for pets. This is done on electric sewing machines. Time taken for this process is

around 20 minutes.
