This document discusses various production scheduling concepts and methods. It defines loading as determining the total time required for operations and adding it to planned workstation utilization. Scheduling determines start/finish times of operations. Master scheduling provides completion times for departments. Benefits of scheduling include inventory reduction and increased efficiency. Gantt charts illustrate project schedules and activities. Other concepts covered include line of balance, linear scheduling method, batch production scheduling, MRP, Kanban, dispatching, progress reporting, and manufacturing lead time.

Production planning, routing, scheduling, Activating, MonitoringDarshan Shah
First Plan Your Work and then Work on Your Plan.
1. Planning is deciding in advance what to do, how to do it, when to do it and who is to do it.
Planning bridges the gap from where we are, to where we want to go. It makes it possible for things to occur which would not otherwise happen.
2. Routing may be defined as the selection of path which each part of the product will follow, which being transformed from raw material to finished products.
Routing determines the most advantageous path to be followed from department to department and machine to machine till raw material gets its final shape.
3. Scheduling determines the program for the operations. Scheduling may be defined as ‘the fixation of time and date for each operation’ as well as it determines the sequence of operations to be followed.
4. Activating is concerned with the starting the processes. Activating is ‘release of orders and instruction for the starting of production for any item in acceptance with the route sheet and schedule charts’.
5. Monitoring is related to report daily the progress of work in each shop in a prescribed proforma and to investigate the causes of deviations from the planned performance.
This topic is related to Material requirement planning, MRP.

The Master Production Schedule (MPS) is a plan for the production of individual final items. The MPS breaks down the production plan to show, in each period, the quantity to produce of each final article.

Model Attribute Check Company Auto PropertyCeline George
In Odoo, the multi-company feature allows you to manage multiple companies within a single Odoo database instance. Each company can have its own configurations while still sharing common resources such as products, customers, and suppliers.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

4. LOADING
4
Once the route has been established, the work required can be
loaded against the selected machine or workstation.
The total time required to perform the operation is computed by
multiplying the unit operation times given on the standard process
sheet by the number of parts to be processed.
This total time is then added to the work already planned for the
workstation.
This is the function of loading, and it results in a tabulated list or
chart showing the planned utilization of the machines or
workstations in the plant
5. SCHEDULING
5
Scheduling is the last of the planning functions.
It determines when an operation is to be performed, or when
work is to be completed; the difference lies in the detail of the
scheduling procedure.
In a centralized control situation - where all process planning,
loading, and scheduling for the plant are done in a central office-
the details of the schedule may specify the starting and finishing
time for an operation.
On the other hand, the central schedule may simply give a
completion time for the work in a given department.
9. Production Control
Perpetual loading
Tabulation of the time necessary to finish unfulfilled orders and determine
how long it will take to finish this work.
Perpetual loading
10. LINE OF BALANCE
Find a feasible defined replacement for all undefined (‘ANY’)
ergonomic constraints on workstations, i.e. one compatible with
the ergonomic constraints and precedence constraints defined on
operations, as well as zoning constraints and possible drifting
operations
Solve the within-workstation scheduling problem on all
workstations, for all products being assembled on the line
Assign the operations to workstations to achieve the best average
balance, while keeping the peak times at a manageable level.
11. Linear Scheduling Method
Linear Scheduling Method (LSM) is a graphical scheduling method focusing
on continuous resource utilization in repetitive activities. It is believed that it
originally adopted the idea of Line-Of-Balance method.
The main advantages of LSM over Critical Path Method (CPM) is its underlying
idea of keeping resources continuously at work. In other words, it schedules
activities in such a way that:
1. resource utilization is maximized;
2. interruption in on-going process is minimized, including hiring-and-firing; and
3. the effect of the learning curve phenomenon is minimized
12. BATCH PRODUCTION SCHEDULING
Batch production scheduling is the practice of planning and scheduling
of batch manufacturing processes.
Although, scheduling may apply to traditionally continuous processes,
such as refining, it is especially important for batch processes such as
those for pharmaceutical active ingredients, biotechnology processes
and many specialty chemical processes.
Batch production scheduling shares some concepts and techniques with
finite capacity scheduling which has been applied to many
manufacturing problems.
The specific issues of scheduling batch manufacturing processes have
generated considerable industrial and academic interest
15. DISPATCHING
Authorizing the start of an operation on the shop floor is the
function of dispatching.
This function may be centralized or decentralized.
The departmental dispatcher would authorize the start of
each of the machine operations – the dispatch actions are
based on the foreman’s routing and scheduling of the work
through his department.This is decentralized dispatching.
16. PROGRESS REPORTING AND EXPEDITING
The manufacturing activity of a plant is said to be “in
control” when the actual performance is within the
objectives of the planned performance.
When jobs are started and completed on schedule, there
should be very little, if any, concern about the meeting of
commitments.
Optimum operation of the plant, however, is attained only if
the original plan has been carefully prepared to utilize the
manufacturing facilities fully and effectively.
