A reoccurring challenge in comparing and combining diverse time series in demand forecasting is the “scale” – as it is in combining metrics. Rescaling is a powerful but simple method to help with this issue enabling demand planners to focus on similarities of shape. This blog provides an example of one method called normalization.
In this blog, we point the reader to a recent article “Humachine”, which identifies the general challenge of implementing decision technology to improve SCM decision making resulting in improved organizational performance and the importance of experience in the trenches.
In this blog we briefly cover some key insights for successful time series forecasting: (a) Profiling the Shape of the Curve is the first stage, and the first step is assessing if the time series is stationary. (b) The forecast method identified must capture the shape and be able to project the shape across time. (c) There are limits in historical and no amount of “fancy math” can overcome them.
Learn when it is time to move from RCCP to LP Genie for your CPE as part of your organization’s journey pulling from years in the trenches and current ongoing activities with clients.
For a new technology to be successful it requires the correct seasoning which requires time in the trenches. This blog captures lessons from two past gurus.
Monte Carlo Discrete Event Computer Simulation is a particularly powerful and flexible “tool of the trade” for a wide range of challenges in supply chain and operations management. This blog provides some basics on MCDECS, the next blog will use MCDECS to explain why limiting the size of a gathering helps reduce the spread of COVID-19.
Investing in SCM Technology: Sense and Respond – A Vision from A Long Time Ago in A Galaxy Far, Far Away
Having a vision of the future is important to help coordinate SCM initiatives towards the “global good” – but having a vision is worthless without effective work in the trenches. In fact, a far better vision is “sense and respond” SAR which moves an organization from a big bang paradigm periodic driven approach that currently dominates SCM even in best in class organizations to an “as needed” basis.
Before the current set of analytics and SCM experts, it was the OR/MS profession that drove the development and successful application of analytic and data methods to improve supply chain performance. INFORMS continues to lead in the ongoing challenge of more intelligent and responsive supply chains. In this blog, we will point out some keynote addresses from the current meeting of relevance to successful SCM technology investments.
“Chaos, complexity, and uncertainty” often victimize an organization’s supply chain outstripping the ability of spreadsheet-based tools to respond intelligently. Sounds like 2020? In fact, this comes from one of the original Jedi Knights Dr. Harlan Crowder in a 1997 paper titled “Helpful Hints for OR/MS Consultants”. The purpose of this blog is to revisit this paper since the hints for success are as relevant now as they were then.
The purpose of a vision in this journey is to create a focus on the implementation of decision technology as tools to overcome inherent organizational cognitive limitations of bounded rationality and uncertainty bias to improve SCM. This blog provides some critical lessons to protect a firm’s investment in technology.
