This chapter provides a foundational understanding of inventory management in production processes, focusing on inventory classification, performance measurement indicators, and cost valuation methods. It introduces key concepts such as economic order quantity (EOQ) and manufacturing order quantity, and explains their role in minimizing total inventory management costs. Additionally, it explores the concept of reorder points (ROP) and safety stock calculations, highlighting adjustments required under demand and lead time uncertainties. Illustrative examples are given for better comprehensio...

This document is a detailed exercise correction for managing inventory within production processes. It tackles multiple computations, including annual demand, optimal order quantity using Wilson's formula, and economic production quantities for various scenarios such as cost minimization. Comparative decisions are analyzed for production in-house versus outsourcing, supported by cost formulas and numerical examples. The document also provides advanced safety stock calculations to meet service level goals in specific case studies.

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 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. The document highlights the need for strategic flexibility and effective planning tools for m...
