An emphasis is placed on decision-making grounded in evidence and optimizing relationships with stakeh...
This document evaluates methodologies for developing an industrial and commercial plan (PIC) while comparing the strategies of pursuit and leveling. It provides a breakdown of demand forecasting, workforce requirements, and associated costs under varying conditions. The 'pursuit strategy' is noted for its flexibility, while the 'level strategy' is more cost-effective and ensures production stability. A recommendation is made for the level strategy if cost savings and production rhythm are prioritized, but storage capacity considerations influence the strategy choice.
This document focuses on the elaboration and evaluation of two strategies for industrial and commercial planning: the level strategy and the chase strategy. It includes a summary of theoretical foundations, computations, and cost analyses associated with each approach. For a company producing a single product, calculations such as staff wages, hiring and firing costs, inventory holding expenses, and end-of-year stock requirements are outlined. The level strategy is recommended for its cost-efficiency and production stability, while the chase strategy is evaluated for flexibility and storage...
The document presents exercises and detailed solutions focusing on inventory management in production processes. Using given parameters like demand, storage costs, and delivery times, calculations include optimal order quantity using Wilson's formula, safety stock, and economic production quantities. The analysis identifies inefficiencies in current processes and provides recommendations such as determining the advantages of outsourcing production. Additionally, statistical models are applied to calculate safety stock to ensure a defined service level.
This chapter explores demand forecasting in production systems. It outlines the importance of reliable forecasting for planning and decision-making, introduces types of demand profiles, and explains quantitative and qualitative forecasting methods. Core methodologies include decomposition of demand into trend, seasonality, and residual elements and exponential smoothing techniques. Evaluation metrics such as error mean and mean absolute deviation (MAD) are detailed to assess forecasting accuracy.
This chapter explores the concept of demand forecasting as a critical tool for production system management. It categorizes demand into distinct profiles and outlines quantitative forecasting techniques, including trend estimation using the least squares method, seasonal coefficient analysis, and residual factors. Emphasis is given to multipliers incorporating trend, seasonality, and randomness, alongside the exponential smoothing method to refine predictions iteratively. Finally, the accuracy of forecasting methods is evaluated using measures like average error and mean absolute deviation...
This document explores the methodologies for industrial and commercial planning (PIC) as well as production master planning (PDP). The PIC acts as a high-level agreement between production and commercial teams to predict and balance sales, production resources, and inventory strategies. It outlines strategies (level strategy and pursuit strategy) to efficiently forecast resource allocation such as labor, machine capacity, and inventory based on anticipated variations in demand and stock requirements. The document transitions to the PDP, a short-term plan focused on converting PIC forecasts...
The document focuses on forecasting future demand for a business using historical data from 2019. Key methodologies include graphical trend analysis, decomposition method to estimate trend and seasonality, seasonal coefficient calculation, and error metrics like absolute mean error (EAM) and exponential smoothing models with alpha values of 0.1 and 0.2. Results indicate a seasonal upward trend in demand, with the corrected forecasts matching demand more accurately, and the recommended model for accuracy is exponential smoothing with alpha = 0.1.
This document provides a comparative framework for studying two production planning strategies: the pursuit strategy and the level strategy, as applied in an industrial and commercial plan (PIC). Methodologically, it outlines key concepts such as forecasting, stock management, and production scheduling, culminating in cost analyses for both strategies. The findings address workforce and storage constraints, enabling stakeholders to determine optimal planning strategies under real-world limitations.
