Abstract
A linear programming model for integrated production planning study for methods, procedures and
practices of a South African bread producing firm. The study considers the entire planning activity in the
firm as an integrated process involving several closely related functions. The mathematical modelling
considers production costs, production throughput rates, customer specifications and demands, sales
process and facility capacities and designs an optimal production planning. The firm produces two
perishable products that should be stored for fixed periods. There is a series a of vehicles responsible for
delivering the products from the firm to distribution centers in specific quantities. Computation of results
and analysis reveals that the integrated methodology is feasible and practical.
Keywords
Production planning, distribution planning, supply chain management, Baking industry, integrated systems.
1. Introduction
In the past years, managers in the food industry have encountered difficulties and to instantaneously reform, adapt and
up their game as they were faced with international changes within the food industry, because of safety regulations
and legislations, advancement in technology, market globalization and emerging quality objectives. Organizations are
now placed under pressure to improve certain aspects in their businesses such as manufacturing, quality control,
marketing, etc. Managers need to understand that such changes, need to be accompanied by supply chain management,
to ensure that the control process does not halt at the manufacture but continues to distribution and after sales firms.
The goal of supply chain is to efficiently create a link between suppliers, producers, distributors, storage facilities,
sellers and customers (Liang, 2008), Therefore supply chain integration should provide the end customer with
maximum value of quality products, while coordinating a balance between requirements of customers with materials
coming from suppliers, including supply chain issues of designing low cost products, and keeping inventory at a
minimum.
This paper takes a supply chain management approach, the paper takes a discussion on the facilities and processes that
are required in the production and delivery of products from supplier to customers at a bakery that process pita bread
and wraps. The paper further illustrates Scheduling and management of raw materials, manufacturing, packing, storage
and distribution services.
1.1 The case study.
The bakery is a supplier of pita bread and Wraps, it also specializes in producing Shawarma’s and hamburgers. The
bakery supplies major retail stores, including coffee shops and supermarkets.
When analyzing the bakery there mainly two areas that stand out, the production area and the distribution Scheduling
area. Production planning that is carried out by the production manager, addressing and tackling decisions of how to
