Final answer:
Traditional materials-requirement-planning inventory systems are often manual, relying on paper-based records with frequent physical inventory counts. They require accurate forecasting for inventory needs and are generally not integrated with other systems, making them time-consuming and error-prone. The correct option is 1.
Step-by-step explanation:
The characteristics of a traditional materials-requirement-planning (MRP) inventory system include several key points that affect how inventory is managed.
Firstly, traditional MRP systems can be more manual and may rely on paper-based records, which can lead to being time-consuming and prone to errors.
Secondly, these systems depend on accurate forecasting to predict inventory needs, meaning that any inaccuracies in demand forecasting can significantly affect inventory levels and potentially lead to overstocking or stockouts.
Thirdly, frequent physical counts of inventory are necessary to maintain data accuracy since these systems often do not integrate in real-time with other systems or technologies.
Lastly, because of the manual nature and lack of integration, traditional MRP systems do not easily adapt to changes and can result in operational inefficiencies.
