Job Cat Egory Prioritization and Selection in PT.MAI 88 Using Analytical Hierarchy Process (AHP)

PT. MAI 88, one of the government company divisions in the Pekanbaru City which operates in the fields of Public Works, Spatial Planning, Housing, Settlement Areas and Land. PT.MAI 88 experienced difficulties, namely that material resources were not allocated properly. With the main aim of prioritizing the procurement of goods for road and bridge construction maintenance, this research focuses on one of the uses of Multicriteria Decision Making (MCDM), namely the Analytical Hierarchy Process (AHP) to determine the ranking of each construction goods procurement job. The AHP method itself has been discussed with stakeholders involved in the project. It has four categories and thirteen subcategories that have been determined and lead to 12 job alternatives. The results of the AHP show that the criteria with the highest weight starts from Urgency followed by Public Satisfaction, Quality, and Cost Management. Then for the Sub criteria with the highest weight, namely Reports from local public, followed by Traffic Management, Long-term Durability and Reliability, Compliance with specifications and Standards, Labor Cost, Public Safety, Rent Construction Equipment, Resources Availability, Material Cost, Public Engagement and Communication, Stakeholder Expectations, Ease of Installation and Integration, and finally Subcontractor Cost. The alternatives with the highest weight are Procurement of Road Signs, Procurement of “Urugan Pilihan”, Procurement of Base A Stones, Procurement of Base B Stones, Procurement of Several Construction Equipment, Procurement of Asphalt Concrete Binder Course, Procurement of Non-subsidized diesel fuel , Procurement of Dump Truck, Procurement of Binder Absorbent layer, Procurement of material for Culvert Channels and Boxes, Procurement of Construction Retaining Wall, Procurement of Cementation Work.

Deficiencies in and Alternatives to Heat Map Risk Matrices for Project Risk Prioritization

Heat map risk matrices are widely used to prioritize risks. They are Standard Operating Tools for risk management as prescribed by the Project Management Institute (PMI), International Council on Systems Engineering (INCOSE), and many other organizations. They are widely used in projects and programs structured for product development, business, construction, R & D, medicine, and politics. However, they suffer from several weaknesses, notably subjectivity, symmetry, category prioritization reversal, and a failure to account for Risk Aversion, which often dominates how individuals and companies feel about risk. Because of this, they can lead to serious mis-prioritization and mismanagement of risks. We propose an alternative to the standard risk matrix that accounts for these deficiencies and provides a significantly better risk prioritization tool. Two field trials were conducted to demonstrate the benefits of the alternative method for project managers.

Setting research priorities in tobacco control: a stakeholder engagement project.

Background and AimsThe Cochrane Tobacco Addiction Group (TAG) conducts systematic reviews of the evidence for tobacco cessation and prevention interventions. In 2016 TAG conducted a priority‐setting, stakeholder engagement project to identify where further research is needed in the areas of tobacco control and smoking cessation.DesignThe project comprised two surveys and a workshop. A range of stakeholders participated, including members of the public (smokers and ex‐smokers), clinicians, researchers, research funders, health‐care commissioners and public health organizations. The first survey phase identified unanswered research questions in the field of tobacco control. The second phase asked participants to rank these, with overall rankings calculated by combining scores across participants. The workshop allowed attendees to discuss prioritization of topics and questions in more depth. Workshop discussions were transcribed and analysed thematically, and a final voting activity at the close of the workshop allowed participants to choose topics to prioritize and to de‐prioritize.FindingsA total of 304 stakeholders (researchers, health professionals, smokers and ex‐smokers, guideline developers, research funders and policymakers, representing 28 countries) identified 183 unanswered research questions. These were categorized into 15 research categories. A total of 175 participants prioritized categories and questions in the second survey phase, with ‘electronic cigarettes’; ‘addressing inequalities’; and ‘mental health and other substance abuse’ prioritized as the top three categories. Forty‐three stakeholders attended the workshop and discussed reasons for and against category prioritization. Prioritized research categories largely mirrored those in the survey stage, although ‘treatment delivery’ also emerged as a key category. Five cross‐cutting themes emerged: efficacy; relative efficacy; cost effectiveness; addressing inequalities; and different types of evidence.ConclusionsThere are many unanswered questions in the field of tobacco control. Stakeholders highlighted electronic cigarettes, addressing inequalities and mental health and other substance abuse as key areas for further research, and efficacy, relative efficacy, cost‐effectiveness and use of non‐randomized studies as important themes cutting across research areas. Future prioritization work would benefit from targeting non‐US and non‐UK stakeholders explicitly and from examining where priorities may differ based on stakeholder group.

Attentional accounting: Voluntary spatial attention increases budget category prioritization.

Too often, people fail to prioritize the most important activities, life domains, and budget categories. One reason for misplaced priorities, we argue, is that activities and categories people have frequently or recently attended to seem higher priority than other activities and categories. In Experiment 1, participants were cued to direct voluntary spatial attention toward 1 side of a screen while images depicting different budget categories were presented: 1 category on the cued side and 1 on the noncued side of the screen. Participants rated cued budget categories as higher priority than noncued budget categories. Cued attention also increased perceived distinctiveness, and a mediation model was consistent with the hypothesis that distinctiveness mediates the effect of cued attention on prioritization. Experiment 2 orthogonally manipulated 2 components of a spatial cuing manipulation-heightened visual attention and heightened mental attention-to examine how each influences prioritization. Visual attention and mental attention additively increased prioritization. In Experiment 3, attention increased prioritization even when prioritization decisions were incentivized, and even when heightened attention was isolated from primacy and recency. Across experiments, cued categories were prioritized more than noncued categories even though measures were taken to disguise the purpose of the experiments and manipulate attention incidentally (i.e., as a by-product of an unrelated task).

Managing Ancillary Transportation Assets: The State of the Practice

Historically, transportation asset management has focused more on pavements and bridges, and less on ancillary assets such as traffic signs and guardrails. This paper synthesizes the state of practice of ancillary transportation asset management to assess the needs for successful implementation of such programs by highlighting data collection strategies and costs, data analysis tools, and data use in decision making, especially as it relates to asset prioritization and quantifying the benefits of ancillary asset management. The paper focuses on 10 asset classes selected from a review of literature: culverts, earth retaining structures, guardrails, mitigation features, pavement markings, sidewalks and curbs, street lighting, traffic signals, traffic signs, and utilities and manholes. The findings indicate that a number of agencies are making significant efforts to manage these assets with a range of asset management policies, system/program integration approaches, data collection methods and costs, benefit quantification, and asset category prioritization approaches. The results highlight the state of practice of managing ancillary transportation assets, revealing the dynamic nature of these activities as agencies evolve their activities to higher levels of program maturity.

A Throughput Model of IEEE 802.11aa Intra-Access Category Prioritization

In this paper the first saturation throughput model of an IEEE 802.11 network is presented, which includes the intra-access category prioritization introduced in the recently approved IEEE 802.11aa standard. This new feature was proposed to support finer grained prioritization of audio video streams in comparison to the existing Enhanced Distributed Channel Access (EDCA) function. The presented model implements different transmission probabilities for the primary and alternate voice and video queues. Additionally, it includes such features as virtual collision handling, backoff differentiation, and Arbitration Inter-Frame Space differentiation. The presented results show the difference in the operation of IEEE 802.11aa intra-access category prioritization and EDCA inter-access category prioritization. They also allow to derive several novel conclusions.
