Designing Rhythmic Industrial Production (original) (raw)
Production Planning and Control
For efficient, effective and economical operation in a manufacturing unit of an organization, it is essential to integrate the production planning and control system. Production planning and subsequent production control follow adaption of product design and finalization of a production process. Production planning is an activity that is performed before the actual production process takes place. It involves determining the schedule of production, sequence of operations, economic batch quantities, and also the dispatching priorities for sequencing of jobs. Production control is mainly involved in implementing production schedules and is the corollary to short-term production planning or scheduling. Production control includes initiating production, dispatching items, progressing and then finally reporting back to production planning. In general terms, production planning means planning of the work to be done later and production control refers to working out or the implementation of the plan.
Approaches on the Operational Performance of Production Systems
2011
In our approach, we would like to begin with the definition of the performance given by the group L'Afnor, national and international operator in France in the service of enterprises" and civil society"s performance and sustainable development, according to which "performance measures the effectiveness and / or efficiency of a process or of a portion of it, or of a real (or simulated) system, according to a rule, a plan or a goal settled through a company"s strategy". This type of evaluation must reach the purpose for which it was created, namely to implement the company strategy and communication of the project and the vision of the enterprise. In this way, the management of the company together with its employees will be able to focus on ways to implement the project and the correlation of operational initiatives and actions.
Modern methods used in production-operations management
Production–operation management. The chosen aspects, 2021
Climate change, resource depletion, technical progress, growing consumer awareness and changing requirements causes companies to look for new production methods. They may concern various areas of the company’s activity, starting from product design, procurement organization, optimization of production processes, control of manufactured products and services, through improvement of work organization and reduction of production costs, and ending with the implementation of modern solutions based on digital technologies. The purpose of implementing new production methods is to improve labour mobility, optimization of the use of raw materials and resources, costs reduction, increase efficiency, productivity, etc. In the literature, there are many different types of methods that can be used by modern enterprises. It is practically impossible to present all methods in this study. The authors focused on the presentation of selected methods, which are characterized on the one hand by innovat...

Planning model of production process in a manufacturing enterprise
Research in Logistics and Production
The article focuses primarily on two major aspects affecting each manufacturing enterprise. Namely, the question of planning of production process as well as process preparation to manufacture a desired product will be discussed. The article shows planning and production actions on the example of a production enterprise. The technical scope necessary in preparation of each production was presented as well as selected ways for inseparable connections and machines found in manufacturing halls were discussed. The characteristics of an enterprises manufacturing metal workshop furniture as well as workshop cars equipment was shown. The course of manufacturing process planning was depicted. Due to presented plans of the production hall it is possible to view the whole process. Some changes in that plan to streamline production and extend it in the future with a new range of products were suggested.
System Safety: Human - Technical Facility - Environment, 2019
Assurance of the supervised conditions in all processes affects directly both products and users safety and environmental influence. ISO 9001 and ISO 14001 standards in Operation point require from organisations to implement and control the planned processes by establishing processes’ criteria, assuring the supervised conditions and verifying processes’ conformity. Moreover, in Planning section it is required to plan the processes with the consideration of quality and environmental risk. Therefore research on the practical solutions of operational planning and control in the production processes are of the crucial meaning, especially from the perspective of the integrated fulfilment of the requirements. That is why the value of the paper is being constituted by the authorial methodology of identification of the key-operational criteria, including integrated risk assessment, using the computer support and being a starting point for assurance of the supervised conditions in the key-pr...
Production Planning and Control: The Dissemination Tool of the Operation Strategy
2016
The objective of this research is to analyze the Production Planning and Control (PPC) as a dissemination tool of the operation strategy in industries that compete in environmental sustainability. We used a qualitative methodology supported by cases studies, based on interviews with managers responsible for the production planning and control of four big Brazilian industries. The results indicated that PPC can be an efficient tool to dissiminate the operation strategy for its power of integration with the many key areas involved in an industry, what can bring pratical implications to the ones responsible for the formulation and implementation of the operation strategy. The result is of value because PPC can be used as an ally of the operation/production managers to promote and lead the implementation of the operation strategy on the shop floor.
The Role of Production Planning in Enhancing an Efficient Manufacturing System – An Overview
E3S Web of Conferences
Every manufacturing system can only survive with a high level of system planning and budgeting. Production planning is a sequential ladder in the manufacturing setting to ensure that materials input (raw materials, men, money, and machine) is made available within a stipulated time frame, in the appropriate amount to produce the demanded output of goods and services based on the schedule specified. Production planning also helps in making available high quality of goods and services in the right quantities to the customer at the demanded delivery timing to attain higher degree of customer satisfaction. Through production planning, different departmental activities i.e., engineering, production, purchasing, sales, and marketing, as well as stock control department, and other units that may relate to production are coordinated to attain a regular, steady, and balanced flow of production thus, enhancing reduction in production cycle time. Production planning serves as an instrument whi...
The method of analysis in production management
2007
The method of analysis was developed by ancient Greek geometers to identify and solve problems related to geometry. From that period, well known scientists such as Newton and Descartes have applied the method. More recently, Polya has presented the method of analysis as a heuristic template to solve mathematical and other problems. Despite its continual epistemological dilution, the method has also been used to explain the cognitive process of designing. In this paper it is claimed that the method of analysis can also explain production management. It seems that the method of analysis has been used across different levels of management in production, i.e. from a holistic/strategic perspective through to detailed levels. Therefore, the aim of this paper is to discuss whether the method of analysis provides a partial theoretical foundation for production planning. The research approach is literature review with an emphasis on the method of analysis and synthesis. The conclusion is that the method of analysis and synthesis adds to the theoretical explanation of both design and production.

Technical innovations in the area of manufacturing logistics are being introduced partially and thus not exploiting their full potential. In order to optimise the efficiency of turning manufacturing processes, the process has been analysed and fundamentally re-engineered. All data from production (operations, quantities, date, time duration of operations, etc.) are now located in ERP system. It provided the necessary condition for the establishment of a robust dynamic planning model. An update was required for the whole lifecycle of products and means of work. The paper presents the information support and an algorithm for a dynamic planning model, based on a genetic algorithm. Continuous data capturing and planning in real time are a breakthrough in the management of the process. Presented are a generalised dynamic planning model and a case example from the production of turned parts, which take account of the singularities of a real environment. Production capacities have to be linked up with the supply chain and customers. The presented dynamic planning model can be adapted to various types of production.

We study in this paper the flexible manufacturing systems (FMS) short-term planning problem. It consists of decomposing the initial demand in different cyclic steady states to reduce the complexity of the general planning and scheduling problem. The main criterion to optimize is the makespan. We give a mathematical formulation of the short-term planning problem using cyclic production. However the resulting problem is a non-linear one with integer variables and non linear constraints. To solve the problem, we first make linear the model by generating a database enumerating all the possible cyclic production horizons and their characteristics. Therefore, the remaining variables are the number of steady states, their characteristics (production) and the number of cycles. We have developed an enumerative method which provides, under several assumptions, the optimal solution. We compare then our results with those obtained by the Ohl's approach (1994) and show that the method developed in this paper provides good results

Organizational, Systems and Human Issues in Production Planning, Scheduling and Control
International Series in Operations Research & Management Science
With global markets and global competition, pressures are placed on manufacturing organizations to compress order fulfillment times, meet delivery commitments consistently and also maintain efficiency in operations to address cost issues. This chapter argues for a process perspective on planning, scheduling and control that integrates organizational planning structures, information systems as well as human decision makers. The chapter begins with a reconsideration of the gap between theory and practice, in particular for classical scheduling theory and hierarchical production planning and control. A number of the key studies of industrial practice are then described and their implications noted. A recent model of scheduling practice derived from a detailed study of real businesses is described. Socio-technical concepts are then introduced and their implications for the design and management of planning, scheduling and control systems are discussed. The implications of adopting a process perspective are noted along with insights from knowledge management. An overview is presented of a methodology for the (re-)design of planning, scheduling and control systems that integrates organizational, system and human perspectives. The most important messages from the chapter are then summarized.
