The past few years have seen the utilization of integrated software packages (ERP type) in numerous enterprises. We can thus speak of a large-scale diffusion of the integrated enterprise resource management approach, which induces a growing interest in mastering techniques and approaches put in place in the production planning field, notably collaborative sales and operations planning, master production scheduling, material requirements planning, and implementation control of the plans established.
This book adopts this perspective, focusing on the techniques and approaches that contend with decision-making for short- and medium-term planning, and short-term production and inventory control. The application examples that accompany the presentation of each technique would allow students to acquire a good understanding of the links between the concepts, techniques, and their use in practice.
For the practice exercises and problems at the end of each chapter, students can deepen their grasp of the role played by production and inventory planning and control in a manufacturing company’s supply chain management, sharpening their skills in applying :
The decision support tools and techniques that are implemented in the production planning domain; and
The relevant information in decision-making situations.
In other words, this book would allow students to obtain the knowledge and know-how that are essential in the competitiveness of a manufacturing firm.

Preface by Gilles Paché

For those who are closely interested in the evolution of contemporary economies, there is little doubt about a profound change in value chains in a context of generalized dematerialization of exchanges. Some do not even hesitate to speak of a dominant service model where the production of market and non-market services has totally taken precedence over manufacturing production as if the world of physical objects referred to a bygone past when Taylorism and Fordism triumphed. Nonetheless, it will have been enough for a health crisis on an exceptional scale, at the turn of the years 2020-2021, to remind us brutally that albeit important, services, especially delivery, turn out to be quite useless when the manufacture of physical objects is interrupted. Let us think here of the stockouts of protective masks and artificial respirators which plunged health systems into disarray for several weeks… As for the “salvation” itself in response to the Covid-19 pandemic, it will ultimately come from miraculous vaccines produced in factories running at “full capacity,” day and night. In short, let us not hesitate to speak of a triumphant revenge for manufacturing activity!
Attentive analysts of the functioning of value chains will not be surprised by the centrality of physical objects. Nor will consumers themselves if they think for a moment of the smartphone which they consult frantically several hundred times a day, of the motor vehicle which takes them to work each morning, of the laptop computer which accompanies them to their vacation spot to finish a file in progress, of the barbecue around which they gather their colleagues and friends on weekends… That is a Prévert- style list (of disparate items) that would occupy us for hours if we had to list the physical objects that feed our daily lives. Objects resulting from industrial processes involve materials and component sup- ply, more or less complex assembly, and physical distribution activities to serve the markets, notably through Internet sales. Such a manufacturing reality may appear trivial. It tends to be forgotten or, at least, understated, in favor of the aforementioned service economy. However, that overlooks the fact that the “production of services,” known under the notion of servuction, introduced by the late Pierre Eiglier and Éric Langeard, requires the presence of physical objects to be fully operational.
This means that André Tchokogué’s book comes at the right time to highlight the key elements related to the planning and control of production and inventory of physical objects. The author, a professor working at HEC Montréal, is part of this generation of researchers paying particular attention to oper- ations management. In an academic world where the research work of many academics is often obscure and largely disconnected from the needs of companies, the author stands out with a didactic posture at all times. Such quality emerges with even more brilliance in the present manual, which makes it a remarkable working tool.

Production and Inventory Planning and Control


In effect, it is rare that readers can have in hand a book that harmoniously combines theory and practice. Most often, the authors choose one or the other of the two options: for some, a conceptual reflection on the transformations of industrial systems; for others, a series of operational advice sometimes akin, alas, to “cooking recipes.” André Tchokogué manages the feat of combining total mastery of theory and practice. He perfectly knows the academic literature and wisely mobilizes it to highlight the main issues involved. In regular contact with practitioners, he is able to identify the problems encountered by manufacturing companies and the solutions, possible or not, to overcome them. Moreover, as a planner for three years in the pharmaceutical industry, André Tchokogué has developed real expertise in the implementation of the techniques and approaches presented. He demonstrates an ability to formulate very realistic exercises and applications (which is not always the case in works on operations manage- ment), allowing students in particular to “put into practice” effectively. From this point of view, there is no doubt that the book will very quickly present itself as an indispensable support for easy learning of planning techniques which are essential but sometimes difficult at first.
Finally, we congratulate ourselves on the deep managerial culture which André Tchokogué proves to allow him to avoid falling into the double trap of “confetti specialization” and “temporal myopia.” “Confetti specialization” is currently plaguing the academic community by leading in particular to a focus of research on micro-subjects of relative interest, while “temporal myopia” consists in making a clean sweep of all that may have been developed, thought out, or tested more than ten years ago, even if it means constantly reinventing the wheel! By contrast, the author demonstrates wisdom and a broad analytical view by embracing the issues of operations management in all their systemic complexity. He also immerses himself in seminal works, which are certainly old but which we must consider essential to have an enlightened understanding of today’s questions... and avoid repeating yesterday’s mistakes. After all, as George Santayana reminded us, “those who cannot remember the past are doomed to repeat it.” As such, we would like to thank André Tchokogué for putting in our hands a reference work that will be very useful for students, but also, more broadly, for decision-makers in business.
