    　Resilience,which is a new concept in safety management and crisis management,stands for the ability of a system to absorb changes and disturbances and to sustain its functionality. Resilience engineering is an academic area for studying methodologies how resilience can be implemented into systems.Having experienced many tragic events in the last decades,resilience engineering has been proposed to answer the people’s request that preparedness of the society for the unanticipated should be enhanced further.As an introduction to resilience engineering, this article is to present the story why resilience engineering was born and to explain basic concepts and terms in resilience engineering.

  • Resilience of Urban System and Artifact Against Natural Disaster Risk
    Tatsuya ITOI
    Article type: Invited Article

    　Risk of an urban system and/or artifacts under threat of natural hazards can be estimated by analyzing resilience of a system as well as hazards at the site of the system.What are expected from society to urban system and artifacts can shift over time.Scientific knowledge on natural hazards also grows and sometimes shifts over time.Then,it is proposed in this paper that resilience of a complex system can be defined as “an ability of a system to adapt to a changing situation in a timely manner to continuously achieve its objectives and requirements during its lifetime”.Leadership and management capabilities of various stakeholders are also considered to be important for resilience.

  • Meta-definition of Resilience and Disaster Resilience of Urban Sociotechnical Systems
    Taro KANNO
    Article type: Invited Article

    　This paper firstly outlines “resilience engineering” derived from two different fields,safety engineering and earthquake engineering,and provides a meta-definition of resilience that comprehends various aspects and arguments around resilience engineering in a consistent way.Then,this paper introduces a human-centric modeling framework of urban sociotechnical systems that provides a new and easy-to-use categorization of multiple and complicated interdependencies underlying urban cities,followed by an introduction to a simulation study for the evaluation of disaster resilience of cities considering civil life,industry activities,critical infrastructures,and the multiple interdependencies among them.

  • Assessment of Resilience in Energy System with Computational Simulation Model
    Ryoichi KOMIYAMA
    Article type: Invited Article

    　This paper presents a quantitative analysis of resilience in energy system by employing an energy security evaluation model and electricity and petroleum supply models.The energy security model deals with uncertainties such as fuel price volatility and fuel import disruption as well as the blackout of nuclear power plants,which analyzes the economic validity of petroleum and LNG stockpiles and nuclear power with a stochastic dynamic programming technique.The electricity and petroleum supply models do a quantitative analysis of optimal electricity and petroleum supply strategy against capital-epicentered disaster and anticipated damage.The results suggest that deployable diversification of LNGcombined cycle,reinforcement of inter-regional power line and optimal operation of petroleum stockpile are effective measures to compensate the supply disruption.Computational simulation analysis plays an important role for designing optimal resilience policy against emerging risks in international security,natural disaster and environmental problem.

    　Our company has been pushing for SQC education since 2010 with the aim of improving the quality of work and upgrading our technical power.
    　Starting in 2016, we have been promoting the use of IoT. Therefore, the need for big data analyses is rising apart from conventional sampling data analyses.
    　As a way for big data analyses, it has become necessary for our company to master machine learning.
    　For that purpose, we are examining how we can implement the education of machine learning that will meet the need of our company as well as individuals.
    　This report highlights the detail of our efforts.

Survey and Field Study Paper
  • A Systematization of Means for Enhancing Activities to Prevent People from Intentionally not Following Rules in Hospitals：with a Focus on Intentionally not Following Safety Rules

    　Considering that intentionally not following the rules which have been set in each workplace makes it difficult to ensure medication safety, MIBM proposed by Nagai et al is an effective method to identify the areas to be enhanced to prevent people from intentionally not following rules, and the whole structure of concreate means for enhancing the organizational activities have not been clarified well, this study conducted a survey on 56 hospitals of different sizes in Japan, and based on the results, systematized means useful for enhancing the four activities focused by MIBM. As the results, it was found that most hospitals cannot thoroughly implement the four activities, implementation status of means for enhancing the activities is different hospital-by-hospital, appropriate combination of means enables hospitals to enhance their activities, and the effectiveness of individual mean depends on size of hospital except means for enhancing activity “monitoring and instructing of not following rules in workplaces.” Application of MIBM with taking these results into considerations can be expected to make the activities more fit to each hospital.
