Quantitative Analysis in Operations Management

Alistair Brandon-Jones

Nigel Slack

Making decisions and bearing the responsibility for them is one of the cornerstones of any operation manager’s job and its importance is reflected in most texts on the subject. For example, Slack, Chambers and Johnston’sOperations Management provides concepts that support decision making in four major areas: operations strategy, design, planning and control, and improvement. In common with other authors, they explore both qualitative and quantitative approaches, but the lack of space means some aspects of quantitative analysis are not fully explored or are omitted entirely. This is where Quantitative Analysis in Operations Management comes in.

So what do we mean by quantitative analysis? Quantitative analysis involves collecting data that can exist in a range of magnitudes and therefore can be measured in some way. Data then can be organised in such a way as to help decision making. Quantitative Analysis in Operations Management is designed to give you a headstart in the subject and introduce you to the key quantitative methods that are essential to the decision-making process for every operations manager. Packed with examples and exercises this book provides the perfect practice ground for anyone tackling quantitative methods for the first time, or all those looking to brush up their quantitative knowledge!
