Job Shop is process planning in which a cross-sequence of production, machinery, and equipment is arranged by type of product work. The factory layout is structured to support multiple production flows.

Job Shop Features

The following are some of the characteristics of a job shop, as follows:

Number of semi-finished products (work in process) tends to be larger
Requires detailed production planning and control
Production and material handling equipment can be customized and modified to handle a wide variety of products
The workload of each station is different
The availability of sources in the form of raw materials, labor and equipment must be coordinated through ordering planning
Products are processed in lots or batches

The biggest production time is the waiting time for the material to be processed on a particular machine mesin
Direct workers have more expertise when compared to workers in flow process

Example of a job shop

Examples of products that use a job shop include:

A printer that accepts a limited number of certain poster designs
Fabrication factories that accept orders for the manufacture of equipment with special designs
A clothing factory that makes uniforms with and with a specified amount.

Understanding Flow Shop

Flow Shop is a type of production process that is used for products that are assembled or produced in large quantities and in a row (continuous). The Flow Shop production system uses a production line to produce its products. All products are manufactured to the same standards and processes. Flow Shop Production is often referred to as Mass Production or Mass Production.

Flow Shop Features

The following are the characteristics of the Flow Shop production system:

Have Product Standards and process sequences.
Using special machines and work equipment that has a higher production capacity and level of output.
High production volume.
Shorter production cycle.
Production planning and control is easier to do.
Material handling can be done automatically.
Material inventory can be converted more quickly into sales (sales).

Flow Shop Example

Examples of products that use Flow shop production include the production of apparel or commercial electronic products (TV, Smartphone, DVD Player, Laptop).

Definition of Batch

Batch is open shop, intended to take advantage of economies of scale in processing similar parts simultaneously.Batch shop it can also be discrete (manufacturing), it can be continuous (garment, oil refining, chemical processing). The production flow is clearly not as complex as jobshop, with a lot of use of parts that are repetitive and multipurpose. In this system, the grouping and determination of lots is very crucial.

For Batch or Job Shop Production The importance of scheduling can be very complex, in terms of production scheduling, batchflow, jobshop andcellularprocess have been found. In each case the types of products are normally made and many of them maketoorder. The time required to process each job or product varies from job to job due to differences in time setup and other processing requirements as well as differences in customer order sizes.

Environment batch production is a dynamic environment because orders from customers come continuously and finished products are processed and then delivered to customers on time.

Batch Features

The following are characteristics of a batch production system:

Shorter production time.
Places and Machines are more flexible.
Places and Machines are set to produce products in batch form and the settings are changed again for the next batch.

Features of Batch Production scheduling

Production scheduling has several functions in the production system, these activities are (TeguhBaroto, 2002, p167):

Loading (loading) aims to compromise between the requirements requested with this loading capacity to determine facilities, operators, and equipment.
Sequencing (ordering) aims to prioritize work in processing orders yangm
Dispatching. Giving work orders to each machine or other facility.
Controlling scheduling performance by:
Monitor progress towards fulfillment order in all
Redesign sequencing if there is an error or there is a top priority
UpdateSchedules
The implementation of the schedule usually has new problems that are different from the time of making the schedule, so the schedule must be immediately updated updates if there are new problems that need to be accommodated.
