It is of geat importance to evaluate items based on life cycle assessment (production, comsumption, rubbish). Of our objective is to formualate the mathematical models for the assessment of cost, environment, and recycling. We showed our results as follows.The reliability and maintainability of items (products) of life cycle assessment is essential to such research areas. We discuss the maintained systems with inventories. Over pr yield exceed inventories, but shortage of inventories yields the decrease of the production efficiency. The trade-off for controling the optimal inventory levels is of great import p discussed some polices based on life cycle assessment.Software reliability is of another interest for life cycle assessment. In particular reliability plays an important role in our modem society. We discussed software reliability models and the software release policies based on software life cycle assessment.We discussed the reliability and maintainability of items based on life cycle as assessment, which were the first step works for life cyle assessment. We will discuss the more generalized and sophisticated models and evaluate the performance from the viewpoint of life cycle assessment.

基于生命周期评价(生产、消耗、垃圾)对项目进行评价具有重要意义。我们的目标是形成评估成本、环境和回收利用的数学模型。研究结果如下：生命周期评估项目(产品)的可靠性和维修性是此类研究领域的关键。我们用库存来讨论维护系统。产量超过库存，但库存不足导致生产效率下降。控制最优库存水平的权衡是非常重要的，讨论了基于生命周期评估的一些策略。软件可靠性是生命周期评估的另一个重要方面。尤其是可靠性在我们的现代社会中扮演着重要的角色。讨论了基于软件生命周期评估的软件可靠性模型和软件发布策略，讨论了基于软件生命周期评估的项目可靠性和可维护性，这是软件生命周期评估的第一步工作。我们将讨论更普遍和更复杂的模型，并从生命周期评估的角度对其性能进行评估。
