The demand covering concept captures the influence of the distance on the capability to provide a service to user. It is assumed that demand can be covered by a facility only if the distance between the facility and the place where the user is located with a covering radius. This concept is very
frequently utilised in public services planning. Concepts from Location Science can be used in planning decisions in both public and private sector contexts. Specifically, considerations about demand allocation can provide insightful support to decision-makers. Aimed at students of waste management,
logistics, supply chain and operations management, this case looks at kerbside collection services and neighbourhood recycling points.The case examines elements that constitute a location problem which are represented by: facilities offering a given service; users requiring the service; a location
space, in which facilities can be located and users are situated.It offers readers tangible examples and worked through calculations demonstrating how to use Location Science and plan successfully.The case study looks at the service level the current configuration of the HWRC sites system provide to
local households and provides readers with advice on how to estimate the effects of changes in opening hours on the service provision. Readers are also provided with tables illustrating how to effectively analyse and process the information.
The case study clearly explains how process flow diagrams can be used in both manufacturing and services to show how work is carried out. The authors illustrate how process flow diagrams provide a suitably detailed map of the way work is carried out in an organisation and allow value-adding and
non-value adding activities to be identified. Process flow diagrams also reveal how customer and practice have evolved in a particular work area and allow for process improvements to be identified. Process flow diagrams are a convenient tool for process auditing and process improvements. Aimed at
students on operations management courses, the reader is given a narrative explanation of the process and is given the task of logically developing an overall process flow diagram and assessing the process to see if there are opportunities for improvements. As this is a common exercise when involved
in any improvement programme, this case study allows the reader to develop and practice essential skills.In this case study Mike Simpson and Andrea Genovese promote an understanding of how the work flows through "the system" and assess alternative ways of working and create suitable performance
measures. This case study also looks at customer flows and interactions with the service system.
This case study helps the reader develop an understanding of Linear Programming. It offers the reader a clear explanation of this concept, and demonstrates how it is a useful tool for the allocation of scarce resources. Linear Programming represents a quintessential tool for optimal allocation of
scarce resources among a member of competing activities. The term Linear Programming derives from the fact that both the objective function (expressing the performance that decision that decision-maker wants to optimize) and the constraints (representing limitation to the available resources that
need to be employed for achieving such an objective) can be expressed by means of linear polynomials (namely, degree-1 polynomials). The case study shows how Linear Programming can be applied to production planning and product mix decisions. The authors have created very useful worked examples of
the mathematical model, along with the presentation of a solution using the graphical method. Aimed at students of operations management, the authors offer an explanation of both the objective function and the constraints. They also explore difficult concepts such as linear polynomials. In this case
study Mike Simpson and Andrea Genovese demonstrate how linear programming techniques can tackle practical business problems and assess potential future scenarios. The authors guide readers through the stages of calculations and analysis.
This case study looks at strategic approaches to purchasing. It covers vendor rating, development and consideration of costs.Buying-in a product is often called outsourcing or subcontracting and very often these terms are used interchangeably when in actual fact they are quite different. Purchasing
concerns the acquisition of resources for the organisation so that it can continue to make the products and services the organisation provides to its customers. Essentially, the company purchases materials, a component or item from a supplier.Strategic approaches to purchasing include vendor rating
and development and consideration of costs, quality, delivery, flexibility, technical knowledge and reliability of suppliers. However, an initial consideration is to look at the costs of purchasing an item versus the costs of making the same item within the company. This problem is called the 'Make
or Buy Decision' which this case investigates.Aimed at students on operations management and procurement courses, this case study shows the reader how to analyse the costs of purchasing an item versus the costs of making the same item within the company. Through worked examples and presentations of
difficult concepts such as the Derivation of the Break-even Quantity, Mike Simpson and Andrea Genovese guide the reader through the highly technical approach to such complex purchasing decisions. This case study introduces the reader to essential concepts such as outsourcing and purchasing and also
provides them with essential definitions. The authors also guide readers through critical calculations.
This case study focuses on a UK-based designer knitwear manufacturer and retailer, involved in global outsourcing and retailing activities of own-brand products as well as contract manufacturing for other fashion brands.The case analyses the high environmental impact of the fashion industry, in
terms of its carbon, water and waste footprint. It is under increased pressure from various stakeholders to balance the triple bottom line (TBL); environmental, social and economic needs. The case study highlights the difficulties in managing global supply chains when it comes to corporate social
responsibility and protecting workers' interests. It also illustrates how a region's labour laws and historical relationships with Western clients can embed the importance of ethical behaviour alongside modern cost and lead time cutting demands. The authors examine globally dispersed fashion supply
chains which have potentially negative impacts for people and the planet. It highlights the fact that for fashion businesses, it's a challenge to incorporate sustainability when the critical success factors are cost efficiency and effectiveness. Aimed at students on logistics, supply chain
management and fashion courses, readers are provided with tools and ideas for sustainability and presented with questions about challenges to the fashion industry as well as some interesting suggested solutions.
Planning how a company uses its resources can be done in several ways depending upon the type of company it is and the production processes involved. The case study provides essential guidelines on how to create a successful aggregate plan through analysing stock levels, production rate and customer
demand.Aimed at students on operations management courses, this case study analyses how companies can sell a range of products of the same kind, such as screwdrivers. The authors assess how the same processes and equipment are used to make these products, no matter what size the items are. Thus, all
the products can be scheduled together (aggregated) when they are being pushed through the production system. This improves the company's processes. Mike Simpson and Andrea Genovese have explained the role of stocks in the organization, their effect on break-even points and strategies for managing
them to meet customers' needs. In this case study they present how to transform forecast demand and capacity plans into an aggregate plan, and consider key production questions and issues. The case study also includes graphs for measuring demand against production rate and guides the reader through
the calculations and analysis process through a question and answer format.
This case study examines facility layout which concerns both manufacturing and service operations. Facility layout decisions consider how work areas and storage areas are arranged to minimise the costs of movement of people, materials, equipment and information between departments. There are several
approaches to layout problems (activity matrices, string diagrams, flow diagrams, interrelationship diagrams, relationship charts etc.) but all are concerned with how to reduce costs to a minimum. There are different types of layout which a factory or service provider can use to produce a product or
service and the layout chosen will depend upon the volume produced and the variety of products produced. Through worked examples and fully explained solutions, techniques of how to reduce costs by analysing facility layout are demystified. Aimed at students on operations management courses, the case
presents several approaches to layout problems: activity matrices, string diagrams, flow diagrams, interrelationship diagrams, relationship charts). All are concerned with reducing costs to a minimum. The authors illustrate how facility layout decisions determine the arrangement of work areas and
storage areas. This minimises the costs of movement of people, materials, equipment and information between departments. This case study also provides readers with step by step guidance to determining the optimum layout with the Adjacent Department Method.
The Transportation Problem is a simple freight traffic assignment problem in a many-to-many distribution context. The objective of the problem is to find a minimum cost routing plan for goods from their origins (e.g. their manufacturing plants) to their destinations (e.g. retail points). The
real-life case study is about a third-party transportation firm which has to transfer empty containers from 6 warehouses (located in Birmingham, Leeds, Manchester, Newcastle, Sheffield and York), to 5 destinations (Cardiff, Edinburgh, Felixstowe, Glasgow, Southampton). Mike Simpson and Andrea
Genovese provide readers with a detailed and comprehensive analysis of putting together a transportation plan and work examples of mathematical models. Readers are also presented with a series of tables showing the containers availability at each warehouse location and the situation at each
port.Aimed at students on transport management and logistics courses, the reader is shown how to work out a transportation plan that will minimize the total costs by fulfilling all the requirements. The case study guides the reader through the mathematical models and calculations required to reach a
solution. The authors also look at possible constraints and how to tackle them.This case study provides readers with fundamental knowledge about the Least Cost Method.
The Maintenance Stores Dilemma explores warehouse operations at Vortex, a manufacturer of hi-tech drilling equipment running out of storage space for its maintenance stores operation. Aimed at students on warehouse management courses, it looks at issues such as increasing requirements for new
equipment, shortage of space and the resulting delays to services to clients. It assesses solutions such as proper warehouse planning and the redesign of space in order to improve logistics performance.The author presents a wide variety of problems and the suggested solutions. The Maintenance Stores
Dilemma helps readers put together a sustainable and flexible warehouse operations plan. Gwynne Richards illustrates problems that can arise when managing a warehouse, based on his own experiences of working with a number of clients over the years. Register for a Kogan Page account at check-out to
