Remsoft Open Training in Auckland, NZ

May 7 – 10, 2019

Remsoft will host open training in Auckland, New Zealand from May 7th to May 10th, 2019.

The venue for this training will be:

ACE Computer Training Ltd.
Level 3, 46 Brown Street

Remsoft Open Training sessions are always a big hit and often sell-out. They are taught through demonstration and hands-on modeling exercises. Space is limited so please reserve your seat early.

Modeling Fundamentals (IMF) is the basic introduction to forest modeling using Woodstock. Other than a basic understanding of forestry concepts (silvics, harvesting systems, reforestation methods, etc.) there are no requirements for this class. That said, Fundamentals is an intense 2.5 day course that covers a lot of material. The cost for the 2.5 day course is $2,500 US.

Modeling Fundamentals will be held on Wednesday, May 8 – Friday, May 10.

Modeling Workshops are advanced modeling classes and the expectation is that students are already adept at modeling constructs such as outputs and constraints. Prerequisites are listed for each workshop. Each workshop is an intensive half or full day session, and the cost is $750 US per half day workshop or $1,500 US for a full day workshop.

Modeling Workshops will be held on Tuesday, May 7 & Wednesday, May 8

Allocation Optimizer (WAO) 1/2 day workshop $ 750.00 US

Mixed Integer Programming (WMI) 1/2 day workshop $ 750.00 US

Debugging and Due Diligence (W3D) 1/2 day workshop $ 750.00 US

Tuesday, May 7th

Allocation Optimizer – 8:30 AM – 12:00 PM

Prerequisites: Modeling Fundamentals + 6 months modeling experience

Allocation Optimizer (AO) is an extension to Woodstock to facilitate the development of delivered-price harvest scheduling models. Rather than just determine how and when to harvest trees, an AO model also considers where to deliver products based on the price each destination is paying and the cost to haul it there. Models can be enhanced with additional decisions (harvest systems and crews), product conversions (wood chips), and transport systems (trucks vs barge, etc.). In this workshop we will set up a basic supply chain for a 1-year block harvest schedule, learn to balance production and deliveries, and constrain solutions based on delivery, process and inventory controls.

Mixed Integer Programming – 1:00 PM – 4:30 PM **UPDATED**

Prerequisites: Complete fluency in Woodstock modeling (theme-based outputs, free variables, constraint formulations using array syntax).

In most situations, linear-programming is sufficient to model most forest planning problems. In cases where decisions are discrete (yes/no, all/nothing, etc.), we need to employ mixed-integer programming (MIP). Woodstock offers multiple ways to model discrete decisions through automatic and manual formulations using user-declared variables and constraints. We first cover terminology and syntax and introduce a global discrete decision: which species do we plant (in all planning periods)? Then we look at decisions that change each planning period: of N districts, which M districts should we operate in each period? Next, we look at Woodstock’s controls to force all-or-nothing harvests at both the development type and analysis area unit levels, and how to use these structures using the Control Section and implement them manually. We wrap up with a look at various logic constraints that are the basis for adjacency constraints and road building and a simple linked decisions exercise.

Due Diligence & Debugging – 8:30 AM – 12:00 PM

Prerequisite: Modeling Fundamentals + 6 months modeling experience

The focus of this workshop is how to improve model performance confidence in model results and performance. First, we look at the process of matrix generation itself and the clues it provides about your model: Are your outputs being calculated correctly? Do you have missing yields? Is your model needlessly large because of landscape themes that provide no value? Are all your actions being considered? Next, we look at strategies for debugging your model, and finding errors of omission and commission: Are the transitions creating development types that lack yields? How do you know if a development type is linking to the correct yield table? Finally, we look at various reports and assorted tips that can be used to track down hard-to-find problems in your models.
