Fixed Point Iterations

A cloud provider hosts virtual machines (VMs) of different types, with different resource requirements. There are bounds on the total amounts of each kind of resource that are available. Requests arrive in batches of different sizes. Under the ‘complete blocking’ policy, a request is accepted only if all the VMs in its batch can be accommodated. The ‘partial blocking’ policy would accept a request if there is room for at least one of the VMs in the batch. Blocked requests are lost, with an associated loss of revenue. The trade-offs between costs and benefits are evaluated by means of appropriate models, for which novel solutions based on fixed-point iterations are proposed. The applicability of those solutions is extended, by means of simplifications, to very large-scale systems. Numerical examples and comparisons with simulations are presented.

Purpose The purpose of this paper is to propose a framework of value co-creation in platform ecological circle for cold chain logistics enterprises to guide the transformation and development of cold chain logistics industry. Design/methodology/approach This paper establishes a conceptual framework for the research on the platform ecological circle in cold chain logistics, utilizes a structural equation model to investigate the influencing factors of the value co-creation of the platform ecological circle in the cold chain logistics enterprises and elaborates the internal relations between different influencing factors regarding the value co-creation and enterprises’ performance. Findings Results show that resource sharing in logistics platform ecological circle can stimulate the interaction among enterprises and this produces a positive influence on their dynamic capabilities, which, in turn, affects the they to work together to plan, implement and solve problems, so as to achieve the goal of improving enterprise performance. Practical implications The shared resources and value co-creation activities in the platform ecological circle are very important for the transformation and development of cold chain logistics enterprises. Therefore, enterprises should promote value co-creation through realizing resource sharing and creating a win-win cooperation mechanism. Originality/value This paper targets at incorporating the resource sharing in platform ecological circle for cold chain logistics enterprises, explores from an empirical perspective the role of the resource sharing in cold chain logistics enterprises in enhancing the dynamic capabilities of enterprises, thereby encouraging the value co-creation behavior, and ultimately boosts enterprise performance and stimulates business development.

Abstract This article presents and discusses, in the new context of COVID-19, findings from a tabletop exercise on response and resilience in the ongoing opioid crisis in Pennsylvania. The exercise was organized by [identifying information removed] and held at the Pennsylvania Emergency Management Agency (PEMA), in further collaboration with the Governor’s Office of Homeland Security, the Pennsylvania Department of Health, and with the participation of several additional agencies and institutions. It addressed first-responder and whole-community response and resilience to the ongoing opioid crisis. More than 50 experts participated in the one-day program that involved state and local agencies, first-responder organizations, as well as academia in a discussion about effectuating comprehensive response to overdose incidents. Participant experts represented a wide array of backgrounds, including state and local law enforcement agencies; emergency medical technicians; public health and health care professionals; and scholars from the fields of law, security studies, public policy, and public health, among other relevant areas. Participants addressed specific challenges, including resource sharing among responders; capacity-building for long-term recovery; effective integration of non-traditional partners, such as spontaneous volunteers and donors; and public education and outreach to improve prevention. The exercise aimed to strengthen the whole-community approach to emergency response.
