Approaches towards a generic methodology for storage of hazardous energy carriers and waste products

Energy carriers – either conventional or ‘new’ ones – have to be provided in large amounts to meet the requirements of permanent availability and reliable supply of electricity. Depending on their state of aggregation, energy carriers are either stored in large masses (if solid or liquid) or at elevated pressures (if gaseous). Both impose the hazard of large-scale fire, in the latter case additionally the danger of explosion or unintended release. Very similar hazards occur for wastes. Solid wastes are present in large masses and only a small part is recycled. Most of the solid wastes are used in energy conversion. The main gaseous waste is CO₂. During capturing also the hazard of unintended release exists. In this article, existing approaches for safe storage and fire prevention are discussed and a generic methodology is outlined. This methodology consists of the following steps:

? gaining knowledge about the behaviour of the material stored (reactivity, thermal stability, etc.),

? assessing the environmental conditions for the storage site (neighbourhood, safety distances, etc.),

? assessment of prospective consequences of an incident and

? development of individual loss prevention conceptions.

All steps require both experimental testing and theoretical considerations about accident scenarios as integral parts of the methodology.

试论中小企业库存材料管理存在的问题及应对措施

材料是指企业在生产过程中为销售或耗用而储备的各种有形资产,是企业存货的主要内容,也是构成资产负债表中流动资产的一个重要项目。因此,材料管理的好坏已成为衡量企业管理制度是否完善、材料储备是否合理、流动资金占用是否最佳的重要标志。

"固体废弃物"与"再生原料"概念辨析

分别就《巴塞尔公约》、日本和我国对“废物”定义进行了分析，建议将“waste”翻译为“废弃物”，用“refuse”指代“废物”或“垃圾”；明确了“再生原料”（secondary materials）在不同场合的不同称谓——“再生原料”、“可以作为原料的废物”和“可循环资源（recyclable resources）”。根据“废弃物（waste）”的性质将其划分为“再生原料（secondary materials）”和“废物（refuse）”。对再生原料要进行回收再生循环操作，使其成为再生材料，最后流入市场；对于“废物（refuse）”，则按照环境法规，最终将其以填埋、焚烧等方式回归到自然环境中。     

Optimal safety stock levels of subassemblies and manufacturing components

In order to control the time to market and manufacturing costs, companies produce and purchase many parts and components before receiving customer orders. Consequently, demand forecasting is a critical decision process. Using modular product design and super bills of materials are two effective strategies for developing a reliable demand forecasting process. They reduce the probability of stockouts in diversified production contexts. Furthermore, managing and controlling safety stocks for pre-assembled modules provide an effective solution to the problem of minimizing the effects of forecast errors. This paper develops, evaluates, and applies innovative cost-based analytical models so that the optimal safety stock of modular subassemblies and components in assembly to order and manufacturing to order systems, respectively, can be rapidly quantified. The implementation of the proposed models in two industrial case applications demonstrates that they significantly reduce the safety stock inventory levels and the global logistical cost.
