Abstract
Purpose
This research presents a multiproject scheduling and resource management (MPSRM) model that includes an M/M/c/n queue system, a p-hub median model, a parallel machine scheduling and a hub location problem solution method. This research aims to design a project network and then sequence raw materials delivery to hub factories.
Design/methodology/approach
This research is implemented as a case study in construction and industrial company. It considers several mines to supply raw materials for production in hub factories. In the sequencing phase, a parallel mine scheduling problem specifies the delivery of raw materials to hub factories. Furthermore, a multisource project scheduling model is studied and designed for building project-oriented companies.
Findings
The results suggest that the proposed MPSRM model in this study significantly reduces project transportation costs. Therefore, creating accurate planning in projects, especially in construction projects where transportation plays an important role, can help reduce time and costs. Researchers, project managers and those dealing with projects can use this model to exploit their projects.
Research limitations/implications
When the number of construction projects in a construction company increases in a region, choosing an appropriate strategy to supply resources and raw materials becomes very important in terms of profit and loss and project completion as scheduled. An increase in transportation demands alongside the economic development on the one hand and providing competitive transportation services, on the other hand, have increasingly spotlighted the significance of hub networks in transportation systems. In addition, in this research, there is no suitable access road from the mines to the project sites, and considering the workload, if any of the projects become a hub, a proper road should be built.
Originality/value
To the best of the knowledge, there is no outstanding research in which a p-hub median location problem by considering queuing model and different transportation modes and a parallel machine scheduling problem are studied simultaneously.

Abstract
Purpose
The purpose of this paper is to explore an identified medication error using a root cause analysis and a clinical case study.
Design/methodology/approach
In this paper the authors explore a medication error through the completion of a root cause analysis and case study in an aged care facility.
Findings
Research indicates that medication errors are highly prevalent in aged care and 40 per cent of nursing home patients are regularly receiving at least one potentially inappropriate medicine (Hamilton, 2009; Raban et al., 2014; Shehab et al., 2016). Insufficient patient information, delays in continuing medications, poor communication, the absence of an up-to-date medication chart and missed or significantly delayed doses are all linked to medication errors (Dwyer et al., 2014). Strategies to improve medication management across hospitalisation to medication administration include utilisation of a computerised medication prescription and management system, pharmacist review, direct communication of discharge medication documentation to community pharmacists and staff education and support (Dolanski et al., 2013).
Originality/value
Discussion of the factors impacting on medication errors within aged care facilities may explain why they are prevalent and serve as a basis for strategies to improve medication management and facilitate further research on this topic.
