Based on the analysis of the present situation and the typical problems of the development of the institutional pension service in Shanghai in recent years, the paper puts forward the pertinent suggestions from the aspects of the allocation of the aged resources, the transformation of the government functions, the standardization of the old-age service, the talent incentive and the medical reimbursement.展开更多

In this algorithm, the bottleneck is first scheduled optimally while the non-bottleneck machines are subordinated around the solutions of the bottleneck schedule by some effective dispatching rules. Computational results indicate that the MB heuristic can achieve a better tradeoff between solution quality and computational time compared to SB procedure for medium-size problems. Furthermore, it can obtain a good solution in a short time for large-scale jobshop scheduling problems.展开更多

In this algorithm, a schedule for the bottleneck machine is first constructed optimally and then the non-bottleneck machines are scheduled around the bottleneck schedule by some effective dispatching rules. Computational results show that the modified bottleneck-based procedure can achieve a tradeoff between solution quality and computational time comparing with SB procedure for medium-size problems. Furthermore it can obtain a good solution in quite short time for large-scale scheduling problems.展开更多

The analysis is based on the network simplex algorithm, which gains negative cost graphs by constructing augmented forest structure, then augments flows on the negative cost graphs until the optimal revolution is gained. Bottleneck structure is presented after analyzing the augmented forest structure. The negative cost augmented graphs are constructed with the bottleneck structure. The arcs that block the negative cost augmented graph are the elements of the bottleneck. The bottleneck analysis for the generalized circulation problem, the minimum circulation problem and the circulation problem are discussed respectively as the basal problems, then that for MCPGN is achieved.

However, architects are increasingly being marginalized in these projects, and their roles are constantly being invaded by others. Despite repeated institutional interventions toward remedying this phenomenon, signs are not abating. This article examines the complexity of this phenomenon to explain the inadequacy of institutional interventions to address the problem. This article conceptualizes the phenomenon of marginalization and role invasion as a super wicked problem with six key features. First, the problem has a difficult definition. Second, the solution involves a large structural and economic burden. Third, time is of the essence. Fourth, multiple stakeholders attempting to solve the problem are part of the cause. Fifth, institutional interventions addressing the issue are weak or ill-equipped. Sixth, institutional interventions discount the future irrationally. The implications of this conceptualization for institutional intervention and research are discussed.展开更多

This paper enumerates several public medical institution reform successful countries such as Singapore, the United States, Britain's reform measures, in order to pass the mature experience of western countries for reference, based on China's national conditions, find the reasonable reform. Hope can stimulate public hospitals on diversified reform attempt of stakeholders to invest more resources, create more value, let the state and the public get bigger interest. In the end, improve the national medical and health undertakings.展开更多
